：电流滞环控制具有易于实现、快速的动态响应和无条

件稳定等优点，但该控制方法使逆变器的开关频率不固定，

造成逆变器输出滤波器设计困难，因此很少有文献提及此种

滤波器的设计方法。该文研究了一种基于电流滞环控制的半

桥双降压式逆变器输出滤波器的设计方法。该方法从短路特

性和稳压精度两方面阐述了如何最优选取滤波电感，从谐振

频率和无功补偿两方面阐述了如何最优选取滤波电容-Hysteresis current control method has the

characters of simple implementation, a rapid dynamic response

and unconditional stability. But this control method made the

switching frequency varying widely. So it was difficult to

design the output filter of the inverter. Almost no one has

expressed how to design this kind of output filter. In this paper

a design method of half bridge dual buck inverter’s output filter

based on hysteresis current control was presented. In this

method how to choose the inductor optimally based on short

circuit function and the voltage drop, how to choose the

capacitor optimally based on resonant frequency and the

compensation of reactive power, were presented.
