Abstract
The control device includes: a unit for receiving, for a time period, phase voltage setpoints forming a setpoint vector in vector space; a unit for selecting at least N+1 states of the inverter which are associated, respectively, with at least N+1 predetermined vectors (M1 . . . M27) defining a volume in the vector space (Esp) containing the setpoint vector; a unit for controlling the inverter, over the time period, in order to place it successively in the selected states so that it substantially applies, on average over the time period, the phase voltage setpoints. The at least N+1 states of the inverter are selected from among groups of at least N+1 states of the inverter, the at least N+1 states of the inverter of at least one of the groups being associated, respectively, with at least N+1 predetermined vectors (M1 . . . M27), at least N of which are formed by predetermined zero-sum phase voltages and at least one of which is formed by predetermined nonzero-sum phase voltages.
