Two-Phase Interleaved Boost Converter with ZVT Turn-On for Main Switches and ZCS Turn-Off for Auxiliary Switches Based on One Resonant Loop

A two-phase interleaved boost converter with soft switching is proposed herein. By means of only one auxiliary circuit with two auxiliary switches having zero-current switching (ZCS) turn-on, two main switches are switched on with zero-voltage transition (ZVT) to enhance the overall efficiency.

Description
Summary:A two-phase interleaved boost converter with soft switching is proposed herein. By means of only one auxiliary circuit with two auxiliary switches having zero-current switching (ZCS) turn-on, two main switches are switched on with zero-voltage transition (ZVT) to enhance the overall efficiency. Moreover, a current-balancing circuit with a no current-balancing bus is utilized to render the load current extracted from the two phases as even as possible, so that the system stability is upgraded. In such a study, this converter, having the input of 24 V ± 10 % and the rated output of 36V/6A, was employed to demonstrate the effectiveness of such a converter by experiment.
