Optimization plays a crucial role to bring out a trade-off between the cost and efficiency of permanent magnet motors. Optimization algorithm coupled with analytical magnetic circuit analysis, is one such technique to improve the performance of a motor. However, the non-linear effects like saturation, cross-magnetization, etc. are cumbersome to be modelled analytically. In addition, the interdependency...
Synchronous optimal pulsewidth modulation (SOP) is an emerging modulation technique for medium voltage industrial AC drives. SOP modulates multilevel converters with low device switching frequency while maintaining the quality of machine stator currents. The goal of our study is to implement SOP technique for cascaded nine-level (9L) inverter with average device switching frequency limited to rated...
This paper is focused on the electromagnetic and structural design of high-speed synchronous reluctance (HS-SyR) machines. Both design aspects are equally taken into account due to high speed requirements. Two design procedures, both based on multi-objectives stochastic optimization algorithms (OA) and Finite Element Analysis (FEA), are presented and compared in terms of computational time and quality...
