| 摘 要： | 针对感应加热过程中谐振频率不断变化的问题,在分析传统锁相环频率跟踪的基础上,提出了一种锁相电路与定角控制相结合的逆变器频率跟踪方法.以Matlab/Simulink为仿真工具,对提出的定角控制方法进行了仿真验证,仿真表明该定角控制方法是可行的,能够快速跟踪负载频率变化,保持功率因数角恒定.

| Abstract: | In order to solve the problem about the variety of resonance frequency,this paper introduces a new automatic tracking method of the converter's frequency using PLL and fixed angle control after analyzing the control principle of phase-locked loop of the converter.The simulation of fixed-angle-control is examined based on Matlab/Simulink.Simulation results indicate that this method is feasible.It can quickly track the load frequency and keep the power factor angle. |
