摘要
针对变频调速电动机再生能量回馈应用技术中存在的问题,采用双PWM变频调速技术,设计了一种基于固定开关频率的SVPWM电流控制的PWM整流器,并在机床电力拖动控制系统的应用中取得良好的控制效果。
Aimed to the problem that exists in the motor＇s regeneration energy feedback technology, this paper used the dual-PWM VVVF technology to design a current control PWM-rectifier based on the fixed-switching frequency SVPWM, which has won a very good control results in the application on the machine tool＇s electric drive control system.
