DC-Bus Voltage Control for Single-Phase Active Power Filter using Neural Network

This paper presents the application of neural networks called ADALINE that controls the DC-Bus voltage of the voltage source inverter, which is an active power filter (APF) in the single-phase power system. The DC-Bus voltage control in APF is especially important for maintaining the appropriate voltage level, which is the reference voltage across the capacitor. ADALINE can effectively control the voltage equal to the reference voltage and the APF can inject the compensated current with good performance. The electrical power system has the unity power factor and the source current is close to the sinusoidal. The proposed method has been validated with Simulink/MATLAB.
