Efficiency optimization of PMSM based drive system

The proposed work in this paper is a combination of analytical and numerical methods that are able to calculate the harmonic losses of permanent magnet synchronous machine (PMSM) at any operating point with less execution time and adequate accuracy. Both the fundamental and harmonic losses of the machine in conjunction with the inverter losses are modeled such that the inverter-motor efficiency can be tested for different conditions. Numerical simulation of the field oriented control have been conducted and results include current, modulation index, power factor, switching frequency and all the variables in the drive system. Furthermore, Maximum efficiency control strategy has been chosen such that the drive system can work at the most efficient condition at all operation points. The proposed work is presented in the context of drive system that is based permanent magnet synchronous machine (PMSM). However, the proposed method can be extended to induction motor drive system or any motor use PWM in control of the inverter output voltage.
