چکیده :

Nowadays, power grids typically utilize boost converters to transform energy into the desired form since they operate in continuous conduction mode (CCM) and have slight electromagnetic interference (EMI). Increasing nonlinear loads in modern power grids, which may result in poor power factor, makes applying an ordinary boost converter with solid performance extremely challenging. On the other hand, that traditional controllers, such as PIs, cannot control the converters at all operation points. For this purpose, a fuzzy logic-based controller has been designed using the MATLAB/Simulink platform to enhance the power factor correction (PFC) for a parallel-connected boost converter. According to the result, fuzzy logic-based controllers have been more successful than classical controllers in falling output voltage overshoot and ripple. Additionally, by comparing the proposed method to other traditional controllers, such as PI controllers, the robustness of the controller can be validated irrespective of changes in the system parameters.
