摘　　要：In order to meet the requirements of medium and small power induction heating devices for power supply, a load resonant inverter circuit based on pulse density modulation method is designed. Firstly, the topology and relevant parameters of the circuit are designed, and the full-bridge circuit with high reliability and simple structure and the LCC load resonant inverter circuit are selected. Secondly, the control method is analyzed and a relatively mature pulse density modulation method is adopted. Finally, the circuit is simulated and verified by using MATLAB software. The research results show that the output waveform distortion rate is low, the current fluctuation is small, and the switching device loss is low.
