Abstract :
The design and breadboard implementation of a constant-frequency, zero-voltage-switched (ZVS), full-bridge (FB) PWM converter delivering 12 V at 1 kW output from a 350-450 V DC input bus is described. The ZVS characteristic is maintained over a wide operating range by utilizing the transformer magnetizing inductance as an energy storage element. Output voltage regulation is accomplished entirely on the secondary side through magamp control, thus simplifying the methods used for maintaining control and isolation
