中文摘要	Although the shunt active DC filter (ADF) can effectively suppress the transmission current harmonics in HVDC, the performance requirements of ADF control system are very high. This paper utilizes a high-gain feedback control method in ADF and defines the parameters of the control system. Additionally, a controller based on digital signal processor (DSP) and field programmable gate array (FPGA) is designed for the system. The phase-locked loop (PLL) is used in the controller for synchronous sampling and control, which can improve the accuracy of harmonic measurement and makes the passband of discrete digital filter autotrack the system frequency. A pulse width modulation logic circuit with small phase shift is realized to satisfy the performance and stability of ADF system. The lab experiment based on the designed control system obtains good harmonic suppression results.
