Abstract
A rectifying circuit includes a first diode coupled between a first terminal configured to receive application of an A.C. voltage and a first terminal configured to deliver a rectified voltage; and an anode-gate thyristor coupled between a second terminal configured to receive application of the A.C. voltage and a second terminal configured to deliver the rectified voltage, wherein an anode of the anode-gate thyristor is connected to the second terminal configured to deliver the rectified voltage.
