摘　　要：将有源、无源电力滤波器结合构成的混合型有源电力滤波器是当今的发展趋势,能够充分利用2种滤波器的优势,在高压大容量条件下对谐波进行补偿。通过对无变压器型混合有源滤波器的设计原则进行了研究,并建立数学模型;在基于电网谐波电流的反馈控制策略下,分析电网侧电感和系统延迟时间对系统稳定性的影响。最后,通过仿真结果的比较,验证了分析的正确性。Active power filter and passive filter combining to hybrid active power filter（HAPF） was the trend,which utilize the advantages of the two above filters sufficiently.It was intended for harmonic compensation in condition of high voltage and large capacity system.The researches were made on design of a transformerless hybrid active power filter,and the mathematical model of HAPF was presented.Two factors were analyzed： the power inductance and the delay time which affect the system stability with source-side harmonic current feedback control.Furthermore,simulation results verified the validity of the analysis.
