Study on static electricity induction load-matched of voltage-source converter for induction heating

Over-compensated and less-compensated three-order resonant circuits which are used in static electricity induction load-matched of voltage-source induction heating converter are analyzed. The ways of design and calculation are given. According to the configuration and respond of circuits, the switches states of inverters are studied. By means of analyzing the switch-loss, the conclusion is provided that, for high frequency voltage-source inverter, over-compensated circuit is better than less-compensated. The simulated and experimental result shows that the conclusion is correct. The guiding designing ways of over-compensated circuit, being used as voltage-source induction heating supply load-matched, are provided
