The traditional induction heating power supply has poor control circuit stability and dynamic control effect. Aimed at the states, MCU S3F9454 is used to be combined with PWM controller SG3525 to strengthen the system adaptability of load parameter variations and external disturbances and achieve more advanced control strategy. This paper introduces the structure of the induction heating power supply, and the software process of the control program. The prototype experimental results show that the design of the control mode is feasible and correct. It changes the traditional heating method, and it is suitable for small power inverter power supply.
