Abstract

See full text

A method of controlling current in a three-phase voltage converter operating in current imbalance mode, the method being:

    determining a setpoint limit value for forward current (Idlim*) as a function of a current capacity of the converter (Ilim) and of forward balanced current (Id*);determining a maximum reverse current value (Iimax) as a function of the determined forward current setpoint limit value (Idlim*) and such that the phase currents are at a maximum; anddetermining a reverse current setpoint limit value (Iilim*) as a function of the maximum value of the reverse current (Iimax) and of a reverse balanced current (Ii*).
