摘要 

研究一种无电解电容功率解耦电路及对应的控制策略。该电路根据电网脉动功率和电机功率之间的关系,实现电网侧和电机侧功率解耦,有效抑制直流母线电压波动。基于该电路工作特性,提出预测控制算法以提高无电解电容驱动系统的功率因数,并简化控制器设计。推导并分析电机转矩脉动的原因,提出一种主动阻尼算法抑制电机转矩脉动,进而提高系统的稳定性。构建基于该新型功率解耦电路的永磁同步电机驱动系统,通过仿真和实验,验证了理论分析的有效性和优越性。

Abstract

This paper presents a novel electrolytic capacitor-less (ECL) power decoupling circuit and control strategy. According to the relationship between the pulsating power of the power grid and the motor power, the circuit realizes power decoupling between the grid and the motor, which effectively suppresses the DC bus voltage fluctuation. Based on the characteristics of this circuit, a predictive control algorithm is proposed to improve the input power factor of the ECL drive system and simplify the controller design. The reason of motor torque ripple is derived and analyzed. An active damping algorithm is proposed to suppress the motor torque ripple, which improves the stability of the system. The permanent magnet synchronous motor (PMSM) drive system is constructed based on this novel circuit. The simulation and experiment show the effectiveness and superiority of theoretical analysis.
