A rectifying circuit and method to produce a DC output by rectifying a sinusoidal source having a plurality of output phase voltages and a plurality of phase-to-phase voltages, the rectifying circuit including a bridge circuit coupled to the output phase voltages, the bridge circuit having a plurality of switches; and a control circuit coupled to the output phase voltages and to the bridge circuit, the control circuit being configured to control the switches in accordance with respective absolute values of the phase-to-phase voltages; wherein the output phase voltages are rectified to produce the DC output. When the sinusoidal source is inductive, switch turn-off may be timed to provide synchronous rectification related to estimates of source periodicity.
