摘要
A reduced-voltage/zero-current transition (RV/ZC-T) PWM converter includes an added active resonant network shunting the active power switch to reduce the switching losses in both the active power and and passive rectifier switches. The active power switch turns-on under reduced-voltage while the rectifier diode turns-off under zero-current. A soft current turn-off of the rectifier makes this converter suitable for high voltage applications where the reverse recovery losses of the diode can be considerable. An auxiliary switch included in the resonant network also operates with zero-current- switching.
