Abstract
The control device of an electric power converter comprises a control device controlling turn-on of semi-conductor legs. The converter comprises DC voltage power supply lines on three levels with two filtering capacitors. The control device supplies modulation signals of control signals of said legs. The control device comprises a regulating circuit to regulate the voltage variation of intermediate voltage via a general control component. The general control component is determined according to modulation signals, to signals representative of DC voltage and to signals representative of currents to take part in regulation of the intermediate voltage. The method processes voltage variation regulation via the general control component.
