摘要:
Disclosed is a DC/DC converter apparatus comprising a full bridge non-resonant pulse-width-modulated (PWM) switching circuit, which includes inductive device(s), clamp diodes, and an output transformer rectifier and filter circuit. Capacitive and diode elements associated with bridge switching devices operate to switch current through the switches at substantially zero voltage (ZVS). The inductor element and clamp diodes are used to reduce the primary transition shoot through current resulting from reverse recovery of the transformer secondary rectification stage while also reducing emi and semiconductor stresses.
