A Bridgeless Cuk-BB-Converter-Based BLDCM Drive for MEV Applications

This article presents a brushless DC motor (BLDCM) drive for maritime electric vehicle (MEV) application. The presented BLDCM uses bridgeless Cuk-buckboost (BL-Cuk-BB) converter input-side power factor (PF) improvement. BL-Cuk-BB the buckboost negative half-cycles of input AC voltages and Cuk positive half-cycles. In case MEVs, systems are generally fed by diesel engine generators (DEGs). asymmetric is operated in discontinuous inductor current mode (DICM) present work to attain better quality. usage second-order with fourth-order results decrement net order system. Additionally, also participates as filter component along capacitor C2 during operation enhance total count reduction achieved eliminating extra/external back-feeding diodes, which used schemes. scheme inbuilt anti-parallel diodes same purpose. lesser components requirement BL-Cuk-BB-converter-based implies cost volume, greater reliability, lower conduction losses, weight drive, adds merits model. paper includes detailed mathematical model stability analysis using pole-zero maps bode plots each half-supply voltage cycle. an EV application has been developed on MATLAB/Simulink platform DICM operation, MATLAB simulation have validation drive.
