Abstract

A zero-current-switching (ZCS) pulse-width-modulation (PWM) interleaved boost dc/dc converter using a ZCS-PWM auxiliary circuit is presented in this paper. All semiconductor devices in the proposed interleaved boost converter operate at ZCS turn on and turn off. Besides operating at constant frequency and reducing commutation losses, the proposed converter has no additional current and voltage stress, and conduction loss in the main switch compared with the hard switching converter counterpart. The proposed interleaved boost dc/dc converter is suitable for high-power application using insulated gate bipolar transistor (IGBT´s). The principle of operation, theoretical analysis, and experimental results of the proposed interleaved boost dc/dc converter, rated 1kW and operating at 40 kHz, are provided in this paper to verify the performance of converters.
