A high-frequency forward DC/DC converter topology with transformer flux balancing capability

The analysis and design of a high-frequency forward DC/DC power converter topology with transformer flux balancing capability is presented. The converter utilizes a main switch for load current commutation and an auxiliary switch for transformer flux balancing. Moreover, the converter topology provides the means to recover the energy associated with the parasitic inductances of the circuit components, thus yielding high efficiency and allowing for high operating frequencies. Experimental results for a 1 kW, 20 kHz prototype unit are presented.<
