一种准开关电容谐振变换器

A quasi-switched-capacitor (QSC) resonant converter is proposed for isolated dc/dc conversion in offline power supply application. Similar to the Φ2 resonant converter, the proposed converter is operated most efficiently at fixed switching frequency and duty ratio, and it features trapezoidal voltage waveforms on all switches. Full soft switching combining ZCS, ZVS on and off is achieved within a ...
