| Abstract |
The study of a 1 kW converter for 120 V bus regulation in a spatial application is proposed. Several converters based on the full bridge inverter topology are evaluated as classic PWM hard switching converter, serie resonant, ZVT PWM, Phase Shift PWM with or without active snubber. Particularly, different full-bridge phase-shift PWM converters that present the best performance are studied and compared. The active controlled clamp option allowing ZVS operation and high efficiency is selected. Then, the study and design of this converter is made, completed by experimental results on 1kW, 100kHz converter. Impacts of the clamp switch command on the efficiency and performance from low load to full load are analysed and tested. |
