Novel Zero-Voltage and Zero-Current-Switching Full-Bridge PWM Converter Using a Simple Auxiliary Circuit
A novel zero-voltage and zero-current-switching (ZVZCS) full-bridge pulsewidth modulation converter is presented to simplify the circuits of the previously presented ZVSCS converters. A simple auxiliary circuit, which consists of one small capacitor and two small diodes, is added in the secondary to provides ZVZCS conditions to primary switches, as well as to clamp secondary rectifier voltage. ...
متن کاملZero-Voltage and Zero-Current-Switching Full-Bridge PWM Converter Using Secondary Active Clamp
A new zero-voltage and zero-current-switching (ZVZCS) full-bridge (FB) pulsewidth modulation (PWM) converter is proposed to improve the performance of the previously presented ZVZCS FB PWM converters. 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 adding any lossy components o...
متن کاملAnalysis 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 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 ...
