摘要
介绍了单周控制的基本原理,详细叙述了单周控制的两种调制方法,对两种方法进行了比较,并分析了电网侧产生电流直流分量的原因。分析结果表明,单极调制能有效地抑制直流分量,是今后有源滤波器控制的发展方向。
The basic principle of one - cycle control and its two modulation methods are introduced. Comparison between these two methods is made and the DC offset presented in line current is analyzed. The results show that unipolar modulation can effectively suppress the DC offset,which will become an effective way of APF(Active Power Filter) control.
