By utilizing a supplementary control switch, which steers the primary current back to the input source to achieve zero voltage switching conditions, a new family of ZVS-PWM converters is derived. The forward ZVS-PWM in single ended configuration is analyzed. High frequency, zero voltage switched, PWM technique is combined with continuous transfer of energy to the secondary, for double ended secondary, for double ended configuration, offering very high power density capability. Experimental results are presented for 300W converter, operating from a large input voltage range of 200V to 400V at 400 KHz switching frequency.
