After more than ten years of technological upgrading and research and development, our company have launched three generations of products for all-digital high-power rectifier controllers .The first generation is full-digital multi-CPU controller, which adopts 196 single chip + 51 single chip computer. It is the first digital control system introduced in the whole industry in China. The second generation is full-digital DSP + CPLD high-speed control system, which has significantly improved in real-time, stability and reliability compared with the first generation. The third generation is the high-precision intelligent control system of all-digital DSP+CPLD, which upgrades the digits of data processing and improves the control accuracy. At the same time, it add the remote online monitoring functions of mobile terminals and PC terminals based on industrial Internet, and takes an important step towards the direction of intellectualization.
