This paper presents the voltage modulation method to reduce switching loss of dual inverters fed open-end wingding interior permanent magnet 

synchronous motor (OEWIPMSM). 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 multilevel 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.
