All-digital intelligent induction heating power supply adopts DSP+CPLD control technology independently developed by our company's team, which is very different from the "pseudo-digital" control technology of DSP+ analog devices currently on the market. The all-digital control technology is from control signal generation, to frequency automatic tracking, to digital PID adjustment, to feedback signals such as frequency, voltage, and current, to data communication exchange, etc., which are all digital signals. At present, most of the digital power supplies on the market use analog devices for frequency tracking and PID adjustment, and the main board and the human-machine interface use DSP communication solutions. From a professional point of view, the DSP in this solution is mainly used for communication and does not participate in core control such as automatic frequency tracking and PID adjustment. This program is an upgraded version of the AVR micro-controller + CD4046 control program developed by our company in the early days. To be precise, this is far from "digital control".
