Two novel quasi-resonant zero voltage switching (ZVS) and zero current switching (ZCS) combined boost converters under constant switching frequency operation are proposed in this research work. With both MOSFETs working under pulse width modulation (PWM) and soft switching conditions, the proposed circuits are able to operate at high switching frequencies with low switching losses and a small component size. The state plane diagram method will be applied for the converter analysis. Converter design as well as computer simulation for analysis validation is presented in this paper.
