摘要
在分析了锁相环的控制原理以及目前使用的锁相定角控制方法的基础上,提出了一种新的锁相控制方法,并将之应用于感应加热电源装置中,实现定角控制。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。
After analyzing the control principle of phase-locked loop and the current use of fixed-angle-control for phase locking, a new control method using phase-locked loop is presented. Then it is applied in induction heating power supply to realize fixed angle-control. Based on MATLAB/Simulink, simulation model of IGBT parallel resonant inverter is established. The simulation results verify the correctness and validity of the phase locking control method.
