Circuit for Converting a Pulsed Input Voltage to a DC Voltage

The present disclosure presents a circuit for converting a pulsed input voltage to a DC output voltage. The circuit comprises input nodes for receiving the pulsed input voltage and output nodes for outputting the DC output voltage. The circuit further comprises a first transistor and a second transistor connected between the input and the output nodes in a synchronous rectifier configuration. The first and second transistors each have a gate connected to a driving circuit configured for alternately charging the gates of the transistors whereby the driving circuit comprises an auxiliary circuit not directly connected to the input nodes and configured for providing a predetermined auxiliary supply voltage to the gates. In an embodiment, the auxiliary circuit comprises a buck DC-DC converter of which an input node is connected to the output nodes and of which an output node is connected to the gates.
