Patent ID: 8295067

Claim:
A power converter comprising: several inputs connected to an energy source and to a rectifier, said rectifier being connected to a power supply bus provided with a positive line and a negative line and to which is applied a DC voltage, a bus capacitor, connected downstream of the rectifier between the positive line and the negative line of the power supply bus, the rectifier comprising a switching leg connected between the positive line and the negative line of the power supply bus, the switching leg comprising at least two transistors connected in series, a connection midpoint situated between two transistors of the switching leg being connected to an input of the converter, via a current limiting element, the transistors being of the normally ON field-effect type and each controlled by a gate control device, wherein each gate control device comprises: an output connected to the gate of the transistor, a voltage rectifier element connected between the output of the gate control device and an input of the converter, upstream of the current limiting element, a capacitor connected between the source of the transistor and a point situated between the output of the gate control device and the voltage rectifier element.
