Analysis and Design Considerations of Zero-Voltage and Zero-Current-Switching (ZVZCS) Full-Bridge PWM Converters
Abstract– In this paper, a detailed analysis of the zerovoltage and zero-current-switching (ZVZCS) full-bridge PWM converters is performed. The differences of the zero-voltage-switching (ZVS) operation between the conventional ZVS full-bridge PWM converters and the ZVZCS full-bridge PWM converters are analyzed in depth. Circuit parameters that affect the soft-switching conditions are examined a...
متن کاملSimulation of a Zero-Voltage-Switching and Zero-Current-Switching Interleaved Boost And Buck Converter
A novel interleaved boost and buck converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristic is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing the common soft-switching module, ...
متن کاملReview of Zero-current Switching Flyback Pwm Dc-dc Converters
Zero-current (ZC) switching pulse-widthmodulated (PWM) flyback DC-DC converter is an extended version of the single switch flyback converter with an additional active circuit. The purpose of the active circuit is to turn-off the main switch with zero-current switching (ZCS) condition to reduce the turn-off switching loss. This paper presents an overview of the ZCS flyback PWM DCDC converters. T...
متن کاملZero Voltage and Zero Current Switching dc-dc converter with active clamping technique
The zero voltage and zero current switching dc-dc converter with active clamping technique is proposed. By adding a secondary active clamp and controlling the clamp switch moderately, ZVS (for leading leg switches) and ZCS (for lagging leg switches) are achieved without any lossy components, the reverse avalanche break down of leading-leg IGHTs or the saturable reactor in the primary. Many adva...
متن کاملA Zero-Voltage and Zero-Current Switching Full Bridge DC–DC Converter With Transformer Isolation
A new primary-side-assisted zero-voltage and zerocurrent switching full bridge dc–dc converter with transformer isolation is proposed. The proposed dc–dc converter uses only one auxiliary transformer and two diodes to obtain ZCS for the leading leg. It has a simple and robust structure, and load current control capability even in short circuit conditions. Possibility of magnetic saturation due ...
