摘　　要：针对变频器不能直接用于快速起动、制动和频繁正反转调速场合的问题,设计了基于DSP控制器—TMS320LF2407A能量回馈控制系统,对能量回馈装置电网电动势前馈的SPWM控制。建立了相关的控制模型,实现了单位功率因数正弦波电流回馈和对电流的精确控制。Based on the fact that general inverter can＇ t meet the need of braking rapidly and the need of running between forward and reverse frequently, an SPWM Senergy - feedback control system based on DSP controller - TMS320LF2407A wh - ich is used for controlling motor control is designed. The control model of system is founded by the technology of grid voltage feed forward and SPWM controling. In this system, unity power factor operation and sinusoidal current feedback are realized.
