It is understood that as early as the 1940s, variable frequency speed control technology for asynchronous motors had already been developed abroad. However, the frequency converters at that time were variable frequency units composed of DC motors and synchronous generators. my country had not yet developed this technology at that time. Frequency converters only appeared in my country after the 1950s. They were first used in flammable workshops such as film factories, where variable frequency units were used to achieve AC speed control.
Static frequency converters composed of power electronic devices only appeared internationally in the 1960s. In 1963, the Shanghai Rectifier Factory developed China's first thyristor. In 1965, my country began researching thyristor frequency converters. Until the 1980s, many universities and research institutes in China actively developed GTR frequency converters, and later further developed IGBT frequency converters, transferring the technology to enterprises for production. However, due to the lack of automated production lines, they were unable to produce high-reliability frequency converters.
By the early 1990s, the deepening of reform and opening up enabled Chinese domestic enterprises to recognize the role of frequency converters and begin experimenting with foreign frequency converters. Foreign frequency converter products, such as those from ABB, Siemens, Fuji, Mitsubishi, Yaskawa, Omron, and Schneider Electric, officially flooded the Chinese market. At this time, the first batch of domestic frequency converter manufacturers also emerged. Anbangxin was founded against this historical backdrop and environment, becoming one of the first frequency converter manufacturers approved by the Ministry of Electronics Industry of China.
In 1988, the first low-voltage frequency converter, SVF, from Japan's Sanken Corporation entered China. At the same time, Fuji frequency converters sold in my country were the G5/P5, which were comparable to the 130G frequency converter in performance and reliability. Following this, frequency converters from Taiwan entered the mainland market. By 2000, there were many frequency converter manufacturers in my country.
Founded in 1998, Anbangxin was among the first frequency converter manufacturers in China. It pioneered the independent research and development of a complete production line and technology for its G-series variable frequency speed control devices, and built a production workshop of nearly 10,000 square meters. Technically, it uses high-power transistors (GTRs) for power devices, and its main control CPU, modulation methods, and control strategies (V/F) are all based on the latest technologies both domestically and internationally. It is one of the earliest manufacturers in my country to produce and sell frequency converters on a large scale.
