Abstract

The current embodiments provide a method for controlling an induction machine with a plurality of phases. Each phase may include a plurality of parallel windings and each phase may be associated with a half-bridge. The method may include determining a current in a winding of a first phase. The method may further include determining a phase current on the basis of the current in the winding, and controlling the half-bridge associated with the first phase based on the determined phase current.
