Abstract
A constant frequency full resonant mode dc/dc converter is provided, suitable for use in low voltage, high current dc power distribution systems. The converter comprises a full-bridge inverter, a resonant circuit, an output transformer, an output diode rectifier, a dc output filter, and a control circuit. The resonant circuit consists of a series branch and a parallel branch. The components of the series branch are selected such that close-to-maximum voltage gain and a near load independent output voltage of the converter are achieved. The components of the parallel branch are, however, chosen to obtain an overall lagging current at the output of the full-bridge for a desired range of output voltage control and no-load to full-load operating conditions.
