Nowadays, for the purpose of converting energy into the requested form, power grids usually utilize boost converters due to their capability to operate in continuous conduction mode (CCM) as well as having slight electromagnetic interference (EMI). In light of the increase in non-linear loads, which may cause low power factors, applying an ordinary boost converter with solid performance is exceptionally challenging. Due to this, traditional controllers, such as PIs, cannot control converters at all operation points. In this paper for this purpose, the MATLAB/Simulink platform has been used to develop a fuzzy logic controller to boost the power factor correction (PFC) for a parallel-connected boost converter. Consequently, it can be seen that fuzzy-based controllers have been more successful in reducing overshoot and ripple in voltage output than classical controllers. 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.
