Abstract
The invention relates to a power supply control device comprising a configuration comprising a voltage source, a resonant inverter circuit powered by said source and comprising a plurality of switch half-bridges connected to the terminals of capacitor means, said configuration also comprising means for controlling the opening and closing of said switches and means for modifying the chopper frequency, a bridge of diode-forming elements connected between the source and the half-bridges of the inverter circuit, and resonant capacitor means connected between the midpoints of the branches of the diode bridge and the midpoints of the half-bridges of the inverter circuit, the device being characterized in that the resonant means further comprise inductor means connected on either side of the bridge of diode-forming elements.
