Description: ：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.

Description: In this paper, an efficient active power filter (APF) scheme is developed to estimate and compensate for harmonic distortion in an electrical power network. The developed APF control scheme is based on a double proportional feedback controller and a single-phase voltage-source half-wave bridge inverter. The proposed filter uses a Multi-layer Artificial Neural Network (MLANN) with a shift method for estimating system harmonic currents and voltages at a dedicated point. The proposed scheme is tested on a 13 bus industrial distribution system. The obtained results ensure the effectiveness of the proposed filter. The system is simulated in MATLAB-Simulink and simulation results prove that the polluting harmonics have been greatly reduced.
