Abstract

This paper presents a novel resonance based modulation strategy for a full-bridge current-fed isolated DC/DC converter for high voltage applications. Output regulation is obtained using variable frequency modulation on the primary side to compensate for line and load variations. A two-step method is used for current commutation and usage of active clamp based snubbers are avoided. Circuit operation under different operating modes in steady state are described in detail. Closed firm expression for the converter gain and other values of interest are derived using state plane concepts. The presence of a discontinuous conduction mode is discussed and the mode boundary is identified. Design steps for arriving at the component values of the converter based on set of specifications is discussed. Proposed concept, operation and derived closed form expressions are validated through simulation.
