中频电源的工作原理为：采用三相桥式全控整流电路将交流电整流为直流电，经电抗器平波后，成为一个恒定的直流电流源，再经单相逆变桥，把直流电流逆变成一定频率（一般为1000至8000Hz）的单相中频电流。负载由感应线圈和补偿电容器组成，连接成并联谐振电路。
The working principle of an intermediate frequency power supply is to use a three-phase bridge fully controlled rectifier circuit to convert AC power into DC power. After being flattened by a reactor, it becomes a constant DC current source. Then, through a single-phase inverter bridge, the DC current is inverted into a single-phase intermediate frequency current of a certain frequency (usually 1000 to 8000Hz). The load is composed of an induction coil and a compensation capacitor, connected into a parallel resonant circuit.
