摘要：

The Full-Bridge Isolated Current Fed Converter with Active Clamp advantages are in its ZVS capability and its well-clamped operation devoid of voltage overshoot on the converter switches and the rectifier diodes. Another relative advantage is that the isolation transformer magnetizing current does not have a DC component. An analysis defines the converter voltage transfer ratio taking into consideration the switches' parasitic capacitance and the transformer leakage and magnetizing inductance, The analysis defines the selection criteria for power stage component values, Two breadboard models were built and tested utilizing; the Current Fed Full Bridge topology, One model was realized as a DC/DC and the other as a single stage PFC, The models' experimental data confirmed calculations.
