PIC Based Controller Single Phase AC/DC Converter purposely deals to control harmonic current components. The purposes of the study are to convert single phase AC to DC for using in non-linear loads. The feedback from non-linear loads will create a harmonic current. This current will affect other surrounding equipment where using same sources and courses damage to electronic part. Proportional integrative (PI) controller is used to control the Pulse Width Modulation (PWM) signal generated. By using PWM technique, the input current will be forced to follow the generated current created by the Active Power Filter (APF) in order to maintain low harmonic distortion while supplying the non-linear load. One-level two pulses PWM circuit topology was used in this study. Computer simulation was implemented to confirm the operational circuit. Comparison in harmonic percentage before and after the implementation of APF will be presented.
