Abstract：In order to solve the problems of three-phase current distortion and high harmonic content during the operation of permanent magnet synchronous motors, this paper proposes a new harmonic current suppression method. Firstly, the expression of each harmonic current in the corresponding synchronous rotating coordinate system was analyzed. Then, a closed-loop harmonic current detection system was designed to extract the harmonic current. Finally, the deadbeat current prediction control strategy was used to suppress harmonic current by generating the compensation voltage. Simulation and experimental results show that this method can effectively suppress the harmonic current and improve the motor’s sinusoidal degree of the three-phase current. Moreover, the calculation is simple and easy to implement.
