Abstract :
A soft switching boost converter with zero-voltage transition (ZVT) main switch using zero-current switching (ZCS) auxiliary switch is proposed. Operating intervals of the converter are presented and analyzed. Design considerations are discussed. A design example with experimental results obtained from a 600 W, 100 kHz, 380 V output, power factor corrected, ac-to-dc, boost converter using insulated gate bipolar transistors (IGBTs) is presented, Results show that the main switch maintains ZVT while the auxiliary switch retains ZCS for the complete specified line and load conditions
