Power Factor Correction of Single Phase Rectifier using Fuzzy Controller

This paper presents the power factor correction of single phase rectifier using fuzzy controller. The main objective are to apply the boost converter to improve power factor of single phase rectifier as unity power factor and to apply the fuzzy controller on Arduino microcontroller controlling this process. The structure of research consists of a 1500 W, 300V, single phase rectifier which includes the power factor correction boost converter with fuzzy controller. Being processed, the dc output voltage of converter is controlled by Fuzzy controller, and generated by multiplying output with dc bus voltage which results to current reference. PWM gate drive of IGBT is obtained by comparing of this current reference with dc bus current. The experimental results show the achievement of dc output voltage regulation control from 300 V and 400 V reference. In addition, the power factor increases as 0.86, and the total harmonic distortion of current decreases as 70 %. Finally, the advantages of this research is ability to apply to the large DC converter and the fuzzy controller parameter is simplify modified and develop to self-tuning controller in the future.
