摘　　要：运用了一种将无源滤波器与有源滤波器串联后再并入电网的结构。分析了并联型混合电力滤波器抑制谐波的原理。采用了单相-三相构造法和瞬时无功理论的谐波检测方法来检测单相系统。有源滤波器的电流控制电路使用数控式滞环比较方式。仿真结果表明,该混合滤波器达到了预期的滤波效果。The frame of parallel hybrid active power filter （HAPF） , which a passive power filter was put in series with an active power filter（APF） , was put in parallel with the power grid. The basic principles of HAPF for suppressing harmonic were analyzed. A new harmonic detection way based on the single-three phase method and in- stantaneous reactive power theory was adopted to detect single-phase power system. The NC-hysteresis comparison was used in the control method of APF circuit. The simulation results show that the hybrid filter achieve the due effect.
