In modern power grid, the active power filter (APF) based on the digital control technology is widely applied in the aspects of improving electric energy quality. Further, in some special applications, it is strict on the power density and cooling. In the paper, the APF with the characteristic of high frequency and self cooling is proposed, which adopted the traditional two-level topology. The power device consists of three-phase full-bridge power silicon carbide (SiC) MOSFET modules, and the control system is integrated with DSP+FPGA control. Eventually, it is promoted in the 20A three-phase four-wire APF.
