The paper design the device of modularized three-level active power filter, completed the structure design of the device and the design of main circuit parameters. According to the theoretical derivation and simulation results, the DC link capacitor parameters, the AC side output filter inductance andresistance parameters and precharge resistor parameters are designed, and the design of the control board based on DSP+FPGA is completed. On the experiment platform the DSP and FPGA procedures of the deadbeat control and neutral-point balance control are completed, and the rationality of the design of the hardware platform and the control effectiveness of all control strategies are verified.
