A novel single-stage DAB power-factor-correction AC/DC converter with voltage feedback

A novel single-stage dual-active-bridge (DAB) power-factor-correction AC/DC converter with voltage feedback is proposed. High efficiency, high power-factor and reduced dc-bus voltage are achieved with less components. A 92/spl sim/132 V input, 48 V/5 A , 100 KHz single-stage DAB power-factor-correction AC/DC converter prototype with voltage feedback has been made to verify this circuit.
