碩士 === 國立海洋大學 === 電子工程學系 === 83 === The waveform in the quasi-square-wave converter (QSC) is square like except during the turn-on and turn-off switching intervals. In order to achieve zero-voltage-switching (ZVS) ,resonant tank elements are added to the PWM converter.We first utilize the isolated circuit topology of ZVS-QSC, adding a transformer to increase input voltage range. It is possible to be utilized in commerical products. In this thesis the analysis of ZVS-QSD can be made. By deriving the small signal equivalent circuit we make clear the relationship among output,input,frequency,and oloadd load varying.
