摘要
为消除和减少大功率整流电路中高次谐波对电力系统的危害,必须对此类整流电路所产生的谐波加以抑制和削弱。文中介绍了三次谐波电流注入法的起源、发展及基本原理。该方法是抑制三相二极管桥式整流器中谐波的新方法。文中还分析了输入电流的特性,最后对该方法的发展进行了展望。
At present, the power systems all over the world are seriously polluted by harmonics and one of the reasons causing the harmonic pollution is that a lot of high-power rectification circuits are applied in power systems. To restrain the damage of high order harmonics out of the high-power rectifying devices to power system, the harmonics should be restrained and weakened. In this paper the origin, development and principle of the third harmonic current injection method which is a new harmonic constraint method applied to three phase bridge rectifiers is presented. The characteristics of input current are analyzed in detail. Finally, the prospect of the development of this kind of harmonics restraint method is outlined.
