摘要
针对常规单相不可控桥式整流电路输入电流存在死区、呈尖顶波的特点 ,提出设计了一种采用软开关环节进行续流 ,使输入电流接近于正弦波的一种控制方法。从而有效地克服和缩小了输入电流的死区范围 ,减少了谐波分量 ,改善了系统的功率因数品质。
In this paper,we presented and designed a control method which adopped a high-frequency flexible switch to make current continued so that the current will approximately be sine wave , according to the characteristic that there were dead area ,fastigium wave in the input current of single-phase ,uncontrollable ,bridge pattern rectifier circuit . So the dead area of current was got over and lessen efficiently , heft of humorous wave was reduced and power factor character of system was improved.
