摘要
本文对去掉直流平波电路的电压型变频器进行了探讨,并利用简单易行的同步检测控制方案来补偿直流纹波引起的输出电流畸变,设计出一种新颖的制动方案来克服停机时带来的电压冲击。
This paper has researched the affection caused by ripple in the inverter without filter capacitor,and designed a kind of simple practical synchronism scheme to adjust three-phase SPWM signals and compensate the affection of ripple brought by moving away the filter capacitor in the inverter. Furthermore,it has put forward a novel quick method of braking which can eliminate the voltage impulse when the induction motor is shut off at the high speed. At last, it has given the experiment result.
