Inverter history development
- Apr 19, 2018 -

After the 1960s, thyristors and their upgraded products were commonly used in power electronic devices. However, its speed control performance can not meet the needs.

Since the 1970s, the pulse-width-modulated variable-voltage-variable-frequency (PWM-VVVF) speed control system has achieved breakthroughs. After the 1980s, the improvement of microprocessor technology made it easy to implement various optimization algorithms.

In the mid-to-late 1980s, the VVVF inverter technology of the developed countries such as the United States, Japan, Germany, and Britain was put into practical use, and commodities were put into the market and widely used. The earliest inverters may have been developed by a Japanese who bought a British patent. However, the United States and Germany rely on the advantages of electronic component production and electronic technology, and high-end products quickly seize the market.

After entering the 21st century, domestic inverters have gradually emerged and are now gradually taking over the high-end market. Shanghai and Shenzhen have become front-line positions for the development of domestic inverters, and a number of well-known domestic inverters such as Inovance inverters, Inventronics inverters, Anbang inverters, and Oerlikon inverters have emerged. Among them, An Bangxin Inverter was established in 1998 and is one of the earliest manufacturers of inverters in China. For more than ten years, Anbang Xinren has built a strong foundation of culture and supported growth. The company passed the ISO9000 quality system certification of the TUV organization earlier and was awarded the “National High-tech Enterprise”. It has been rated as “China's drive customer satisfaction for many years” for many years. Ten domestic brands."
