三相PWM整流器改进直接功率控制
Improved Direct Power Control for Three Phase PWM Rectifier
摘要
Abstract
In PWM rectifier, the active and reactive power changing rate varies with different vector. The reason of poor performance of traditional direct power control(DPC) was analyzed according to the expression of active and reactive power in stationary reference frame. A new switching vector table was proposed. Each vector is divided into two parts where different vectors are applied. The simulation result shows that PWM rectifier using new switching vector table has the advantage of lower THD value, smaller distortion of current, well dynamic characteristics.关键词
