A control system of a polyphase power converter has a regulation device configured to generate a control parameter that includes a drive setpoint value or a pulse duration associated with the drive setpoint value of at least one phase situated in a non-linearity zone of a chart and a control optimization system configured to receive the control parameter generated by the regulation device to control the polyphase power converter to deliver a balanced voltage system. The control optimization system modifies each phase of the control 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.
