Abstract
A control method to be implemented in a power converter, the power converter including an inverter module controlled by a control rule that makes it possible to determine a control voltage to be applied to an electrical load on the basis of a reference control voltage. The control method includes determining a correction value to be applied to the reference control voltage, the correction value being determined from a first filtered voltage obtained by filtering a voltage that is representative of the real measured voltage, and a second filtered voltage obtained by filtering a voltage that is representative of the reference control voltage.
