Abstract :
A new converter topology is proposed which uses voltage overlapping method with certain overlapping period that can theoretically provide smooth and regulated DC output voltage without the need of an output filter. An isolated DC/DC converter prototype with output voltage and current of 2.5 V and 15 A respectively was built to demonstrate its operation. Very low output ripple is observed.
