A novel half-bridge DC-to-DC converter combines the functions of loss-less soft-switching and secondary side output voltage regulation at constant switching frequency. This was made possible by using magnetic amplifiers in series with the rectifier diodes. The primary side switches are driven at constant frequency and 50% duty ratios with small dead-time and the output voltage is regulated by PWM control of the magnetic amplifiers on the secondary side. Experimental results obtained on 200 W-48 V prototype operated at 200 kHz confirm these features.
