Abstract :
By integrating a novel voltage doubler rectifier with a classical current-fed converter, a current-fed push-pull boost converter with voltage doubler (CFBCVD) is presented. In addition to having a non-pulsating input current, recovery of the secondary leakage energy, low output capacitor current ripple, much lower rectifier diode voltage stress, and much higher voltage gain can be obtained. These characteristics make it desirable for high frequency high efficiency high output-voltage applications. To demonstrate its feasibility, a 150 kHz, 36-75 V input and 400 V/400 W output power converter is implemented and tested.
