摘　　要：分析了并联型逆变器定角控制的必要性,提出了一种定角控制的频率跟踪方法,并对其实现进行了研究。以MATLAB/Simulink为工具建立了以IGBT为开关器件的并联谐振型逆变器仿真模型,并对仿真结果进行了分析。仿真结果验证了这种锁相控制方法的正确性和有效性,并设计了样机进行试验验证。The paper analyzed the necessity of fixed-angle-control for parallel resonant inverter and proposed a frequency tracking method for fixed-angle-control. It was used in induction heating power supply and realized fixedangle-control. Simulation model of IGBT parallel resonant inverter based on MATLAB/Simulink was established. The implementation of this method was also studied. The validity of the phase locking control scheme was testified by the simulation results. Then the sample machine was designed and examined.
