N2 - The high-speed permanent magnet synchronous motor (PMSM) has a very high fundamental frequency and a small inductance, so the carrier ratio of the motor driver is low, and the switching of the device will bring large ripple current. For the drive method based on pulse width modulation (PWM), the switching frequency is generally over 10kHz, resulting in high switching loss and slow calculation speed. In order to solve the above problems, this paper proposes a pulse-amplitude modulation (PAM) based on four switch buck-boost (FSBB) topology for driving high-speed PMSM, it makes the switching frequency equal to the motor's fundamental frequency. The controller calculation becomes faster, and the switching loss and current harmonic will be reduced. In order to verify the validity of the PAM method, the loading and the given speed change experiment were carried out, then comparing the influence of PAM, square wave and sine wave drive methods on the electromagnetic performance through the simulation. The results show that the PAM drive method based on FSBB has better performance and high efficiency under high-speed PMSM.
