The author designs a high-frequency series induction heating power supply based on PWM chip SG3525, which is controlled by the power control circuit and frequency auto-tracking circuit. Power control and frequency regulation are researched detailedly. The operation results show that the power supply has such advantages as frequency auto-tracking,excellent reliability,high efficiency and small switch loss. It can be widely used in small and medium power applications.
