The invention relates to a control method and system intended to reduce the common-mode current in a power converter which comprises a rectifier stage (') connected to a number of input phases (R, S, T) and an inverter stage (&#x2032;) connected to a number of output phases (U, V, W). On each switching period, the rectifier stage (&#x2032;) and the inverter stage (&#x2032;) are controlled in a synchronized manner so that a variation of potential applied to an input phase (R, S, T) always corresponds to a variation of potential of the same sign applied to an output phase (U, V, W).

Control method and system for reducing the common-mode current in a power converter

A device controlling a JFET power electronic switch of normally ON type, including a main gate control circuit powered by a main power source for driving the gate of the JFET switch, a protection switching device that is switchable between two states, an auxiliary circuit controlling the switching device, and an auxiliary power source whose positive terminal is connected to the source of the JFET switch and whose negative terminal is connected to the gate of the JFET switch, bypassing the gate control circuit in one of the two positions of the switching device. The switching device can be an electromagnetic or electronic switch.
