Permanent magnet synchronous machines (PMSMs) have got a wide range of application in different power ratings and different reliability levels required. To satisfy the requirements for a wide range of the applications, while increasing the system reliability and power ratings and decreasing the weight, cost and repair time, modular motor drives for PMSMs could play an important role in improving the maturity of the technology. However, parallel operation of motor drives will introduce other challenges to the system, some of which will increase the power losses and reduce the system efficiency. There have been some solutions for similar issues in the literature, but not all of them can be applied in PMSM drive applications for the limits associated with specific applications. So, in this paper, a throughout review has been performed on solutions to mitigate the parallelization challenges which is accompanied by relative stability analysis for software-based methods.
