Application of a Modified Non-Bridged Cuk Converter for an Active PF Improved BLDC Motor Drive

This article illustrates a dual-stage modified non-bridged (NB) Cuk converter used power factor (PF) ameliorated BLDC Motor (BLDCM) drive with lesser components. Supply-side unity PF is a goal that the suggested BLDCM drive has the potential to attain. Mains side inductance, which reduces mains current disturbances and removes the need for additional filters to correct mains current harmonics, is a feature of the improved NB-Cuk converter-powered BLDCM drive. The provided modified non-bridged Cuk converter has less parts, which not only makes the driver smaller but also lowers the cost of making it. A MATLAB Simulink simulation model is created to verify the PF ameliorated Cuk converter-powered BLDCM drive that has been suggested. The article's presented adaptive converter is designed to operate in discontinuous conduction mode (DCM). The results of the simulations shown demonstrate the effectiveness of the suggested converter in reaching the intended result.
