【Abstract】 Unified constantfrequency integration(UCI) APF control method is based on onecycle control. This paper presents the basic principle of onecycle control and introduces two modulation methods of UCIAPF and analyzes their features. The reason of DC offset presented in the line current is explained. The results show that unipolar modulation can effectively suppress the DC offset and it is an effective way for UCIAPF modulation.更多还原
