摘　　要：阐述了并联型电力有源滤波器的DSP控制电路在工作过程中受到的各种干扰噪声及其危害,对实验过程中采用的各项硬件和软件抗干扰措施进行了理论和实验研究。为了提高并联型电力有源滤波器的工作稳定性,本文针对APF的具体工作环境和其特性,采取了具体的抗干扰措施有合理选择主电路中IGB模块的缓冲电路结构和参数、采样端口的隔离变压器设计、DSP时钟电路的合理布线等。文章通过实际样机调试和实验,验证了上述各项抗干扰措施的有效性和可行性。This paper presents the noise and its harm in the DSP control circuit of parallel type of active power filter. Some anti-interference measures using various hardware and software are investigated theoretically and experimentally in the experimental process. Based on the specific APF working environment and its characteristic, some measures have been taken in order to improve the parallel type of active power filter working stability, such as reasonable choice of anti-interference measures in the main circuit of the IGB module circuit structure and parameters, the isolated transformer design in sampling port, reasonable cabling of DSP clock circuit, etc. The results from tests verify the feasibility and effectiveness of the proposed method.
