Single-phase APF(Active Power Filter) with one-cycle control has two modulation me-thods-bipolar modulation and unipolar modulation.There are DC off-sets in the compensated source current of the APF with one-cycle control under bipolar modulation.Based on the principle of unipolar modulation APF with one-cycle control,the logic circuit of the controller is designed according to the operation process of the switches.Based on the analysis of global stability condition,the design gist for…
