摘要：
Considering the characteristics of the DC bus voltage control of three-phase four-wire active power filter (APF), a stable-voltage loop and a balance-voltage loop with second-order low pass filter were designed according to the mathematic model of main circuit of system. The purpose of the two loops is to overcome the DC voltage fluctuation and unbalance between up-and-down capacitors during the APF system working. Compared with the traditional PI control method, the proposed strategy can achieve better control performance and control effect proved by theoretical analysis. Experimental results were conducted to validate the effectiveness of the proposed strategy.
