Review 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 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 ...
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 کاملThree-level zero-voltage switching pulse-width modulation DC–DC boost converter with active clamping
DC–DC step-up converters for high-output voltage applications typically demand high voltage devices, leading to high conduction and switching losses. This identified demand has motivated research on active clamping and multi-level topologies. On this context, this study presents the study of a novel DC–DC boost converter with three-level boost-type active clamping, zero-voltage switching (ZVS) ...
متن کاملA Zvs - Pwm Three - Phase Current - Fed Push – Pull Dc – Dc Converter in Microgrids
In this paper, a ZVS-PWM threephase current-fed push–pull dc–dc converter is proposed. When compared to single-phase topologies, the three-phase dc–dc conversion increases the power density, uses the magnetic core of the transformer more efficiently, reduces the stress on switches, and requires smaller filters since the frequency for its design is higher. The proposed converter employs an activ...
