移相式高频感应加热装置的研究

Research on the Phase shift High Frequency Induction Heating Power Supply

提出了一种将移相式调功与锁相时间补偿相结合的控制方案。采用ＣＤ４０４６ 集成锁相环进行闭环锁相控制，并以一台１ｋ Ｗ、频率３５０ｋＨｚ 的实验样机证明了该控制方案的有效性。

A new control scheme is proposed,which combines phase shift power regulation with time compensation during phase locking.A closed loop control is realized with the integrated phase locked loop CD4046.A prototype hardware of 1kW 350kHz is built and successfully tested.
