摘要： A method of controlling of a polyphase power converter driven by an algorithm of the pulse width modulation type, in which a control parameter comprising a drive setpoint value or a pulse duration associated with a value of drive setpoint of at least one phase, situated in a non-linearity zone of a chart, is modified by modifying the value of said parameter so that it is in a linearity zone of the chart. The control parameter of each of the phases is modified in the same manner.
