| Summary: | This project presents the employment of a single-phase active power filter (APF) to
compensate harmonics generated by battery charger. The presence of the harmonics
leads to various problems and poor power quality. The objectives of this project are
to reduce the harmonic distortion of the single-phase system with battery charger
load. The operation of APF is verified using the simulations in Matlab/Simulink.
Conventional proportional-integral-derivative (PID) control based Shunt APF is
being used to regulate the DC bus voltage and hysteresis current controller is
employed to generate signal for switching purpose. The process is based on sensing
line currents, filter currents and DC side capacitor voltage. The error signal caused
by the filter has been computed firstly. Then this error signal has been compensated
using the PID controller. The reference filter currents signal then obtained by
subtracts the line current with the compensated signal from the controller. This
reference current is feed to the hysteresis current controller and compare with the
sensed filter currents to obtain the switching signal for active power filter. Simulation
results are obtained with the conventional PID. The results are compared and
analyzed. The proposed method offers an efficient control method under the varying
load and supply conditions. Based on the simulation and experiment results this
project verified the ability of proposed method to compensate harmonics generated
by the single phase rectifier battery charger. . |
