基于DSP感应加热电源频率跟踪控制的实现

Implementation of Ultra-audio Frequency-tracking Control for Induction Heating Power Supply based on DSP

介绍了在感应加热电源中采用DSP实现超音频频率跟踪的数字锁相环 (DPLL)方法 ,给出了实现DPLL的算法 ,并对采用DPLL的感应加热电源的相位补偿与起动问题进行了探讨 ,最后给出了实验结果 ,验证了该方法的可行性。

A method for implementing the Digital Phase Locked Loop(DPLL) applied to induction heating power supply is put forward in the paper.The process of implementing this method using DSP is presented also.The frequency tracking method based on DPLL,phase compensation method and starting of the induction heating power supply are analyzed.Experimental results verify the correctness of this method.
