Abstract :
A soft switching boost converter with zero-voltage transition for the main switch and zero-current transition for the auxiliary switch is proposed. Various 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, AC-to-DC power factor correction boost converter is presented. Results show that the main switch maintains ZVT while auxiliary switch retains ZCT for the complete specified line and load conditions.
