Design of Single-phase Shunt Active Power Filter Based on ANN

In this paper, a single-phase shunt active power filter (APF) is presented to compensate reactive power and eliminate harmonics in power system. Sensing load current, dc bus voltage, reference dc bus voltage and source voltage compute reference current of APF through modified adaptive artificial neural network (ANN). A modified hysteretic current controller is used to generate the firing pulses of the voltage source inverter which generate reactive and harmonic current to compensate the nonlinear loads. The proposed system is implemented using digital signal processor (DSP). Simulating and experimental results are presented to confirm the validity of the scheme.
