Abstract
This paper presents the voltage modulation method to reduce switching loss of dual inverters fed open-end wingding interior permanent magnet synchronous motor (OEW-IPMSM). the dual inverters motor drive system that employs an open-end winding motor is increasingly used because of its advantages, such as being able to boost a voltage and a multi-level effect caused by the structure of a topology. However, in a dual inverters system, essentially the system operates through two inverters, so an increase of switching loss acts as an inevitable disadvantage of the system. This paper proposes a voltage modulation technique for reducing the switching loss of dual inverter for driving OEW-IPMSM. The proposed voltage modulation method operates on the basis of level-shift and discontinuous pulse width modulation (DPWM) and significantly reduces switching loss compared to the conventional voltage modulation technique of the dual inverters. The validity of the proposed voltage modulation method of dual inverters is verified by the simulation results.
