  • Device and method for controlling an electric power converter
    Patent number: 7505292
    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.

  • Device and method for controlling electric power converter
    Patent number: 7505293
    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.
