[Abstract]: This article provides a detailed overview of the current market demand, market share of various brands, and advantages and disadvantages of domestically produced frequency converters in the domestic industry. It also offers its own perspectives on the marketing strategies of domestic enterprises. 1. Market Situation 1.1 Market Demand Frequency converters, since their introduction in 1964, have undergone more than 30 years of development. They were widely used in major industrialized countries in the 1980s and entered China in the 1990s, finding broad application potential in industries such as air conditioning, elevators, metallurgy, machinery, electronics, petrochemicals, papermaking, and textiles. Especially in energy conservation, their effects are significant. It is estimated that there are currently 42 million fans, pumps, and air conditioning loads operating in China (approximately 10 million of which are fans), accounting for one-third of the country's electricity consumption. 60% of these are suitable for speed regulation. If this portion of the electrical load were converted to frequency converter speed regulation, based on an annual energy saving rate of 25%, the country would save 22 billion kilowatt-hours of electricity annually. According to a 1999 survey by Beijing Kangsi Company, the sales volume of frequency converters in my country has been increasing year by year in recent years, with an annual growth rate as high as 15%, and is expected to reach 7.68 billion RMB in 2005. Specific data is shown in Table 1.2 below. The huge market share of various brands in China has made it a key target for multinational corporations. If the competition among Japanese companies such as Fuji, Mitsubishi, and Sanken a decade or so ago was a fierce battle between Chu and Han, then today, in the 21st century, the competition among multinational corporations for the Chinese frequency converter market has clearly entered a "Warring States" era. Japanese companies entered China early and conducted in-depth research and investigation into the Chinese market, launching products specifically suited to my country's national conditions. Currently, they have the highest market share, exceeding 60%. European and American companies entered later, but their products are high-end, large-capacity, and expensive, holding about 30% of the market share. Less than 10% of the market share is occupied by Taiwanese products (such as Puchuan and Delta). The market share of truly mainland Chinese brands is very low, almost negligible, and their products are of low quality. In terms of product capacity, high-power products account for 5-10% of the market share, while small and medium-power products account for 90-95%. Among them, the 220KW and above are basically monopolized by German Siemens, American AB, GE, Robicon, ABB and other companies; while 85% of the small and medium-capacity products are occupied by Japanese products, such as Fuji, Yaskawa, Sanken, Hitachi, Toshiba, Mitsubishi, Panasonic and other companies. 2. Industry Status Inverters are a high-tech product with high technical content, high added value and high return on investment, which is in line with the national industrial development policy. In recent years, the characteristics of the development of this industry in China are: (1) The number of manufacturers has increased and the development speed is relatively fast, especially in coastal open provinces and cities such as Guangdong, Shandong, Shanghai and Jiangsu. There are dozens of manufacturers, among which the more well-known ones are Ansheng, Shenzhen Puchuan (Taiwan), Anbangxin, Jialing and Senlan in Sichuan, Yantai Huifeng, Nanjing Naite and Guizhou Donggang and other companies. In addition, well-known foreign manufacturers have come to China to form joint ventures and invest in factories to reduce costs and supply the domestic market at better prices, and have already squeezed out a considerable market share, such as ABB, Hitachi, Delta and others. (2). Domestic manufacturers still have a large gap with foreign companies in terms of research and development, process design and manufacturing capabilities of power electronic products. The technology of frequency converters is backward. At present, the domestic frequency converters are of low grade, mainly low voltage (400V) and small capacity (less than 315KW) products. As for frequency converters with advanced functions (including vector control and direct torque control), high voltage (above 3000V) and large capacity (above 1000KW), China is still in the research and development stage and no mature products have been seen. In particular, the high voltage and large capacity type is currently a blank in China. Moreover, the core components are controlled by others. The production of semiconductor power devices required by domestic machines is almost blank and has to rely on imports. (3) The functions of frequency converters are constantly being improved and increased, and the application fields are constantly expanding. From factory equipment to household air conditioners, from heavy machinery to light textile industry, from small power of 0.4KW to large power of 9000KW motors, they have been widely used and have achieved significant economic benefits. 3. Advantages and disadvantages of domestic frequency converters 3.1 Advantages (1) Marketing network advantage. Marketing network is the most powerful weapon for Chinese enterprises to compete with foreign enterprises. Large domestic enterprises have a complete three-level network of company, region and office, and have established offices and user service centers throughout the country. Spare parts are sufficient and services are timely. This is something that foreign enterprises cannot do. (2) Price advantage. Domestic machines are generally 1/5 to 1/3 cheaper than imported machines. If large-scale production is possible, the cost can be further reduced; spare parts are also much cheaper. (3) The product has high technical content and is not much worse than foreign brands. For example, the core components adopt DSP from TI in the United States and IPM from Mitsubishi in Japan. The production process adopts SMT and the management introduces MRPII. Moreover, compared to foreign brands, the localization is better and the design is more suitable for the national conditions, such as wide voltage operating range, wide temperature range design, and Chinese prompt function. See below for a detailed comparison. 3.2 Technical Comparison of Domestic and Imported General-Purpose Frequency Inverters: Power Switching Devices: Mostly use IGBTs, specifically Mitsubishi or Siemens, consistent with imported models. Microcontroller: Mostly use Intel's 87C196MC or TI's DSP, consistent with imported models. Power Capacity: Domestic models can reach over 100 kilowatts, not significantly different from imported models. Frequency Range: Domestic models can reach 400Hz, not significantly different from imported models. Frequency Accuracy: 0.01Hz (below 100Hz), 0.1Hz (above 100Hz), not significantly different from imported models. Voltage Range: 220V, 380V, consistent with imported models. Protection Functions: Multiple protections including overvoltage, undervoltage, overcurrent, short circuit, stall, phase loss, and overheating, not significantly different from imported models. Control functions: It has a screen display of frequency, voltage, current, etc., can add or subtract time arbitrarily between 1 and 999 seconds, contains PID control, and realizes four-quadrant operation, which is not much different from imported machines. Software: The software can be developed or modified according to user requirements to meet the requirements of different users. Imported machines rely on full functionality to meet the requirements of different users. 3.3 Disadvantages The theory of domestic frequency conversion technology is not much worse than that of foreign countries, but in the development and production of frequency converters, due to the weak industrial base of China, the manufacturing technology is not as good as that of developed countries, and the quality of power switching devices is difficult to compete with that of developed countries. At present, there are no fully domestically produced frequency converters. In the field of frequency converters, domestic enterprises are still very young and have a long way to go. (1) Compared with foreign companies, domestic enterprises have entered the field of electrical drive for too short a time, have no flagship products, and have no complete sets of electrical equipment. ABB's ACS-600/1000 series is unique, adopting DTC technology, and is world-leading; Schneider's TE series is a world-leading electrical product, and users may also accept Schneider frequency converters while enjoying high-quality TE series products; Siemens is a long-established European powerhouse with a wide range of applications, and is a well-known brand in the power, electrical drive, financial equipment, and home appliance industries. These three companies can basically provide a complete set of electrical equipment for factories. (2) Domestic frequency converters have just entered the market, and frequency converters have a 3-5 year product maturity period. Whether the quality is reliable and the performance is stable remains to be tested in practice. Few people buy immature products. Foreign brands, which occupy a high market share, have a good market foundation and have a first-mover advantage. This is also the biggest difficulty currently faced by domestic machines. Some domestic brands have poor quality, unstable performance, high return rate, and poor after-sales service, which affects the reputation of domestic equipment and indirectly helps foreign brands. Moreover, some people in China do not trust domestic equipment. 4. Strategy 4.1 Technology Development (1) Develop key components in-house as much as possible, master core technologies, and reduce costs, because the competition between enterprises in products is actually a competition of core technologies. For example, in the domestic air conditioning industry, there are very few manufacturers that truly own variable frequency air conditioning technology. Most of them are joint ventures with foreign companies, so the cost cannot be reduced. According to statistics, the domestic smart chip industry is growing at a rate of 32% per year and will reach US$3 billion in 2005, with a broad market prospect. In fact, in the communications industry, Huawei and ZTE's self-developed chips are a testament to this. (2) Make full use of technological innovation capabilities to develop distinctive and marketable products to achieve "market differentiation" competition. Professor Bert of Harvard University pointed out that market competition mainly relies on "innovation". Whoever can continuously capture better market entry points than competitors can continuously occupy the market. Then, on the basis of stabilizing and improving small and medium capacity inverters, invest in the research and development of high voltage and large capacity products as soon as possible. Only high-end and high-value-added products will have higher profits. 4.2 Market Development The market is a huge system engineering project, consisting of several subsystems. These factors include products, functions, appearance, brand, channels, prices, promotion, marketing, advertising, and services. They have very complex cross-effects and need to be balanced comprehensively. We cannot neglect one aspect for another. (1) Market positioning and pricing. According to the specific situation in my country, the development of domestic frequency converters is relatively late and is in the product growth stage. In the near future, the products should focus on producing and perfecting medium and low power frequency converters, with the goal of meeting the needs of speed regulation and energy saving. High-end products cannot compete with Europe and the United States for the time being; in terms of price, we should follow the principle of small profit and quick turnover to seize the market first. Refer to the standards of our peers and enter the market at low prices to form a scale effect, because a moderate price can give users a sense of trust and increase their loyalty to the product. (2) Strengthen information management. Strengthen market research and promptly grasp first-hand information, such as information on manufacturers of similar products, market dynamics, price intelligence, and demand status of manufacturers, and actively participate in various exhibitions such as the Canton Fair, order fairs, and trade fairs to expand influence. (3) Correctly select channels. Direct channels are user-facing. Large enterprises generally prefer not to cooperate with intermediaries in order to save costs and improve after-sales service and the development of supporting products. Indirect channels involve establishing a wide distribution network and a large marketing team, making full use of the existing channels of intermediaries to quickly enter and occupy the market. (4) Fully improve service quality. The market is fundamentally about service. Domestic brands have an inherent advantage in this regard. Compared with imported products, their service radius is smaller. Large enterprises have a nationwide service network. Before sales, they provide advice and suggestions to users and help them with design and modification. After-sales service is key. A marketing expert once said: the real sales work begins after the product is sold. It is entirely possible to provide follow-up service, conduct regular visits and inspections, keep good records and archives, and improve in a timely manner when problems are found. Even at appropriate times and in appropriate areas, some user parties can be held to strengthen the connection with users. (5) In some situations, users can be allowed to try out the product or even conduct experiments, and some risk commitments can be given to users.
