摘要
基于电阻并联电容消谐法提出了一种新的虚拟电阻并联电容方法。该方法既能取代实际电阻消除谐振,又不消耗能量,提高了系统的效率。分析了整个系统的稳定性,最后做了仿真对比验证,通过调节反馈系数K,能够使经APF补偿后的电源电流THD降低到2.47%左右,证明该方法的有效性。
A new virtual resistance parallel capacitor method based on resistance paralleling capacitor harmonic elimination method was proposed.The method not only can replace the actual resistance to eliminate resonance,but also does not consume energy,and it improved the efficiency of the system.The stability of the system was analyzed,the simulation was done to compare it.By adjusting the feedback factor K,this method can make the supply current THD reduce to about 2.47% after compensation by the APF.The result proves the validity of the method.
