Abstract: A device includes a controllable current source connected between a first node and a first terminal coupled to a cathode of a controllable diode. A capacitor is connected between the first node and a second terminal coupled to an anode of the controllable diode. A first switch is connected between the first node and a third terminal coupled to a gate of the controllable diode. A second switch is connected between the second and third terminals. A first diode is connected between the third terminal and the second terminal, an anode of the first diode being preferably coupled to the third terminal.

Abstract: A rectifying element includes a MOS transistor series-connected with a Schottky diode. A bias voltage is applied between the control terminal of the MOS transistor and the terminal of the Schottky diode opposite to the transistor. A pair of the rectifying elements are substituted for diodes of a rectifying bridge circuit. Alternatively, the control terminal bias is supplied from a cross-coupling against the Schottky diodes. In another implementation, the Schottky diodes are omitted and the bias voltage applied to control terminals of the MOS transistors is switched in response to cross-coupled divided source-drain voltages of the MOS transistors. The circuits form components of a power converter.
