Abstract

A resonant version of the DC-DC forward converter is presented in which both the primary-side switch and the secondary-side diode are either on or off at the same time. Such a topology is capable of operation in the 10-MHz range, and can be used for very-low volume point-of-load conversion in distributed power systems. This type of converter takes advantage of a very low transformer leakage inductance to achieve zero-voltage switching of all its power semiconductor devices. Its resonant ring is also independent of load current. A 50-W prototype operating at 3.6 MHz is presented along with a discussion of the changes necessary to achieve 10 MHz
