摘要
大量电力电子装置的使用,使得公共电网的谐波污染日益加重,因此功率因数校正技术也日益显示出重要性。而三相电源输入设备的功率越大对电网的污染也更大,针对三相双开关管功率因数校正电路拓扑,介绍了一种固定开关频率的谐波注入的控制方案,来达到很好的抑制谐波效果。
The public grid harmonics pollution is increasing with large power electronic devices are used. Therefore the technology of power factor correction is becomeing more and more importance. Three-phase power supply devices make greater pollution with its greater power. A fixed switching frequency harmonics injection control programme, in two switches three-phase power factor correction circuits, which can achieve better results contain harmonics, is introduced.
