碩士 === 大同工學院 === 電機工程研究所 === 81 === In this thesis , a comprehensive analysis of the buck zero- voltage-transition (ZVT) pulse-width-modulated (PWM) coverter is presented . Both active and passive switches achieve zero- voltage switching without significantly increasing their voltage and current stresses . Due operation under the constant frequency , the optimization of the circuit is easily attainable . A novel control approach is introduced . The approach is simple and provides switches with switching. Using results of the dc analysis and dc conversion ratios, a design procedure with the switching property is proposed , and is used to build prototype circuit operating at the switching frequency 296KHz . It has been proven useful for design and when the ZVT PWM converter is implemented at higher frequencies.
