Abstract
Hard-switching is typically used in most DC-DC converters, where transition of a power switch occurs when it still carries current and is subject to voltage at the same time. The hard-switching operation incurs high stress and switching losses to the device. These problems can be alleviated by zero voltage switching in which a power switch is made to turn on and off at zero voltage. This paper presents analysis and design of a Zero-Voltage-Switched (ZVS) quasi-resonant buck converter operating in full-wave mode. The prototype converter is designed and built. Test results show that the designed converter achieves zero voltage switching and possesses good output regulation throughout its operating range.
