| 摘 要： | 传统的并联型有源滤波器(APF)需要检测负载电流,同时计算出其中的谐波及无功分量.该算法较复杂,计算延时大,易导致控制的实时性变差.采用直接电流控制的并联型功率因数校正(PFC),则不需要复杂的算法,它保留了传统APF双环控制的优点上,同时使控制变得简单.此处在分析并联型PFC原理的基础上,进行了仿真,基于DSP控制,...

| Abstract: | In the conventional shunt active power filters,the load current is detected.Then,the harmonic component and the reactive component of the load current need to be calculated and the complex algorithm that will lead to control delay.The shunt PFC used direct current control method does not require a complex algorithm.On the basis of the conventionnal APF double loop,the control will be easy to realize.The shunt PFC based on direct current control is introduced,and simulation is done to test it.Based on the DS... |
