摘　　要：对串联型感应加热电源逆变侧调功技术进行了分析研究,重点讨论了脉宽移相控制技术的工作原理及特点。以MOSFET作为逆变器的开关器件,通过分析脉宽移相控制技术下器件的损耗,来确定移相角的最大取值范围。通过MATLAB仿真和样机实验,对理论分析进行了验证,其结果证明了分析的合理性。This paper analyzed the inverter side power regulation technology of series-resonant high frequency induction heating power supply, discussed the working principle and characteristic of pulse-width phase-shift modulating technique. The paper adopt MOSFET as switch devices, determines the largest scope of the phase- shifting angle by analyzing devices losses. Through MATLAB simulation and experiment tests, the conclusion was proved reasonably.
