Permanent Magnet Synchronous Motor Emulation Based on Quasi-Z Source Inverter

The permanent magnet synchronous motor (PMSM) is widely adopted in the industry. However, current testing systems for PMSM drives exhibit several limitations. This article proposes a quasi-Z source inverter (qZSI) based PMSM emulator, which can emulate a PMSM with different test schemes under different working conditions. The motor emulator (ME) proposed in this paper is able to solve the inherent defects of the traditional inverter. Improve the quality of output voltage and the reliability of inverter system. In this paper, the parameterized model of PMSM and mathematical model of the qZSI are established firstly. Based on that, the PMSM emulator is developed and tested for different operating conditions. Matlab simulations have been used to verify the viability and efficiency of the system.
