整流器死区能量利用方案的研究

The Study of the Way of Using the Dead Area of Rectifier

作为电网中最重要的非线性负载之一,整流器的应用使电网中的正弦波能量变为非正弦波,一部分能量(俗称死区)被浪费掉,变相增加了负载的容量,同时还产生大量的谐波,对电网的安全运行产生了影响。本文对产生死区的原理极其危害进行了分析,并提出了两种提取、利用整流器死区电能的方案。

As one of the most important non-linear load of the grid,the application of rectifier change the sine wave power into non-sinusoidal power,a part of the power（commonly known as the dead area）was wasted,representing an increase of capacity of the load,also generated a large number of harmonics,which impacting on the safe operation of power.In this paper,the principle of producing the dead and the harm of the area are analyzed,also propose two program of extracting and applying the power of the dead area of rectifier.
