A Novel SVPWM Strategy for Open-winding Machine with Low Current Ripples

In this paper, a novel SVPWM strategy for open-winding machine fed by common DC-bus dual two-level 3-phase inverters is proposed to reduce current ripples. In the proposed SVPWM strategy for open-winding, each of six sectors in the space vector plane is further divided into three sub-sectors, in which the optimal effective and zero voltage vector action sequences are found to be different.
