Abstract :
The analysis and design of a high-frequency forward DC/DC 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. The topology provides a means of recovering the energy associated with the parasitic inductances of the circuit components, thus yielding high efficiency and allowing for high operating frequencies. Experimental results are presented for a 1 kW, 20 kHz prototype unit.<>
