Development of Multi-Resonant ZVS High-Frequency Inverter

Abstract

A novel multi-resonant zero-voltage switching high-frequency inverter is developed; this inverter is capable of supplying a current of large amplitude to a load through suppression of the main switch current. The principle of the current ratio of the main switch current to the load current is theoretically proved using the capacitance ratio. The high-frequency operation with zero voltage switching is verified experimentally.
