Control of a three-phase voltage converter in unbalanced mode

The method involves defining (E1) a direct current setpoint limit value (Idlim star) on the basis of a current capacity (Ilim) of a three-phase voltage converter and a balanced direct current (Id star) (E1). A maximum reverse current value (Iimax) is defined (E2) on the basis of the defined direct current setpoint limit value such that the phase currents are at the maximum. A reverse current setpoint limit value (Iilim star) is defined (E3) on the basis of the maximum reverse current value and a balanced reverse current (Ii star). Independent claims are also included for the following: (1) a control device for controlling the current of a three-phase voltage converter operating in unbalanced current mode (2) a computer program for controlling the current of a three-phase voltage converter operating in unbalanced current mode (3) a computer readable recording medium storing a program for controlling the current of a three-phase voltage converter operating in unbalanced current mode.
