Analysis, Design and Implementation of a New Chokeless Interleaved ZVS Forward-Flyback Converter

This paper presents an interleaved active-clamping zero-voltage-switching (ZVS) forward-flyback converter without an output choke. The presented topology has two active-clamping circuits with two separated transformers. Because of the interleaved operation of the converter, the output current ripple will be reduced. The proposed converter can approximately share the total load current between t...

A New Soft Switching Flyback-forward Pwm Dc-dc Converter

This paper presents a new soft switching flyback-forward PWM converter. The proposed circuit employs an auxiliary circuit to achieve soft switching condition for switches and also absorbs the voltage spikes caused by the leakage inductance of transformers in the converter. In the proposed converter main switch operates at ZVS and the auxiliary switch operates at ZCS. The proposed converter has ...

A New Single-Phase Single-Stage AC-DC Stacked Flyback Converter With Active Clamp ZVS

Single-stage AC-DC converters integrate an AC-DC front-end converter with a DC-DC backend converter. Compared with conventional two-stage AC-DC converters, single-stage ACDC converters use less components and only one controller, which is used to regulate the output voltage. As a result, the cost, size and complexity of AC-DC converters can be reduced, but single-stage converters do not perform...
