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,在矿井提升机电力拖动控制系统的应用中取得了良好的控制效果。
In view of problems existing in the applied technology of regeneration energy feedback for variable voltage variable frequency motor,the dual-PWM VVVF technology is used to design a kind of current-controlled PWM rectifier based on the fixed switching frequency SVPWM.Its application to the electric traction control system of mine hoists achieves good control results.
