| Summary: | 碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 94 === A new 3 level auxiliary circuit applicable to converters and inverters is proposed. The auxiliary circuit includes resonant capacitor, resonant inductor and bi-direction switch. This circuit can provide the natural clamp to eliminate oscillation from the leakage inductance of transformer and the soft switching function to both half-bridge converters and inverters. At the same time the switch can operate with zero-voltage switching while turning on. Furthermore, this circuit also provides the function to reduce half of the voltage stress of switch on the inverter application. The proposed circuit was identified with 12V/10A, 120W DC to DC converter and inverter application.
