Optimum Bridgeless Buck Boost Converter Based Bidirectional Charged Electric Vehicles

This article reveals a creativity-filled electric-powered vehicle battery charger. With a focus on V2G and G2V, the technologies used to connect homes and electrical vehicles, it makes advantage of bidirectional on board (EVs). OBCs' affordability and ease of setup are making them more essential for electric cars (EVs). With a little charge period, the vehicle's compact interior and OBC will become incredibly power-dense and efficient. This article models and discusses a dual-stage Pervasive on-board charger and functions effectively throughout a broad input range and output voltages. An all-new bridgeless boost buck converter that may be used as a rectifier or an inverter constitutes the initial phase. It reduces Filtering for common mode electromagnetic interference and both common mode noise and leakage current are maintained at comparatively low levels. In order to guarantee safe battery charging and discharging, galvanic isolation and current regulation are needed, the second stage consists of an isolated bidirectional filter integrated into a direct current converter. Simulation results are shown for a 400- W system running at 200 V rms and 100 V rms input voltages, yielding 46 V dc and 220 V dc outputs, respectively. Results from the simulation show that ac-to-de power conversion can be performed step-down and step-up with peak efficiencies of 96.3% and 95.6%.
