High-Speed Real-Time Power Factor Correction Using Fuzzy Logic Controller

Author : Sathyaprakash B and Susharitha G R

This paper examines the analysis and realtime implementation of a fuzzy logic-based unity power factor correction converter (PFC). The conventional diode bridge rectifier is replaced by a single-phase AC-DC buck-boost converter. Fuzzy logic and Hysteresis control techniques are used to enhance the performance of the buck-boost converter. The fuzzy controller is applied to the DC voltage loop circuit to improve performance. PI and hysteresis controllers are used to control the current loop. The results demonstrate that the fuzzy controller performs well when the robustness of the controller is verified using DSPACE. The experimental findings demonstrate that the proposed controller improved the converter's performance.
