无电解电容和电感PMSM驱动系统控制研究
Research on Control of PMSM Driving System Without Electrolytic Capacitor and Inductor
摘要
Abstract
In a permanent magnet synchronous motor(PMSM)driving system without electrolytic capacitor and inductor,the harmonics on the motor side will affect the front-end input side. In order to solve this problem,a new power factor correction method was proposed to improve the input fundamental frequency current response and reduce input current harmonics. The motor torque control was designed based on the relationship between the input power and the motor torque,which could achieve high power factor operation of the system. The output power response of the inverter was improved in the fast voltage feed-forward control in which the inverter output power was controlled based on the DC link average current,thereby the input current harmonics were reduced. Finally,the effectiveness of the new scheme is verified by experiments.关键词
