Method for controlling an inverter

A module for controlling an inverter configured to power supply a motor, the inverter comprising a plurality of switches controlled to open/close in order to regulate the power supply to the motor,

• each switch having a predetermined time of transition from a closed state to an open state, and a predetermined time of transition from the open state to the closed state,
• the motor comprising a stator and a rotor adapted to be driven in rotation relative to the stator,
• said control module being adapted to:
• generate a first DC digital signal having a first voltage level suitable for controlling the closing of a switch,
• generate a second DC digital signal having a second voltage level suitable for controlling the opening of a switch,
• generate a third cyclic digital signal alternating between the first voltage level and the second voltage level, suitable for controlling successively the closing and the opening of a switch, at a predetermined frequency,
• transmit to each switch one of the digital signals, in accordance with a control law based on a position of the rotor relative to the stator;
• said control module being further adapted to detect a change in the position of the rotor relative to the stator,
• and said control module being configured to delay the execution, from an instant t0 of detecting the change in the position of the rotor, of the control law of the switches controlling the transmission of the third cyclic digital signal to a switch, and the transmission of the first or of the second signal to another switch, as long as said execution produces a command to open one of the switches during a transition from the open state to the closed state of the switch, or a command to close one of the switches during a transition from the closed state to the open state of the switch.
