Abstract :
A new class of zero-current transition (ZCT) and/or zero-voltage transition (ZVT) turn-on and turn-off switching together main switch of the DC-DC converter is presented. In addition, all semiconductor devices operate under soft-switching, and they are not experienced any additional voltage stresses. The new converter is capable of regulating the output voltage for a wide load and input voltage range, while maintaining the stability of the system. The theoretical analysis of a converter is presented and is verified by experiment of 60-600V/15V, 30-300mA DC-DC buck converter. The 18% increase of overall efficiency is achieved with compared to the hard-switching converter.
