dc.description.abstractA novel topology based on linear power amplifiers (PAs) and real-time sinusoidal voltage-adjustment power supply systems (RTSPSs) for a permanent magnet synchronous motor (PMSM) drive system is proposed in this paper. Here, PAs are applied to achieve high-precision motor drive control and minimize the motor torque ripple and harmonic loss caused by nonlinearities of the inverter in traditional space vector pulse-width modulation. Meanwhile, in order to improve the conversion efficiency of PAs, the traditional DC power supply system of PAs is replaced by the RTSPSs, which is based on the wide-band-gap devices. The experimental results show that the efficiency of PAs in the motor system is increased from 58.88% to 79.25%, and the fluctuation of the motor speed at a given speed of 2rpm is reduced from 27rpm to 0.5rpmen_UK
