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 supply lines, an inverter connected between said lines and outputs. The control device comprises a processing unit to supply modulation signals of control signals of said inverter legs. The control device comprises a module for determining a general control component. The module for determining detects a detection signal representative of a highest current signal in absolute value. The detection signal is used to select a modulation signal on which an over-modulation is applied via the general control component. In the method, the detection signal is used to determine a general control component.
