Abstract  Aimat high output voltage waveform with high harmonic content in permanent magnet synchronous motor (PMSM) control system, the additional iron loss of PMSM is increased. In this paper, an improved control method is proposed by adding Boost converter between the rectifier and inverter. Firstly, the mathematical analysis model of PMSM and its control system are established. In order to improve the quality of the output voltage waveform of the variable frequency power supply, the Boost converter is introduced between the rectifier and the inverter of the variable frequency power supply. The simulation model of variable frequency power supply system is established to verify the improved control method. The optimization results show that after the introduction of Boost converter, the quality of output voltage waveform of variable frequency power supply is effectively improved. On this basis, the influence of output voltage harmonic content from variable frequency power supply on iron loss of PMSM is analyzed. Finally, a small-scale variable-frequency power supply with rated output voltage of 24V is designed and manufactured, and an experimental test platform is built to verify the accuracy of the method proposed.
