Modelling of Bidirectional Buck-Boost DC-DC Converter in Electric Vehicles

The design of DC-DC converter in bidirectional mode focuses on achieving cost efficient, compact size, low switching losses. For future sustainable transportation, electric vehicles are crucial things, and Efficient Power management is required for advanced energy usage and better performance. A Bidirectional DC-DC Buck-Boost Converter is very important to Electric vehicle power systems because its energy flow between battery and the auxiliary load. Moreover, the converter's bidirectional capacity allows for regenerative braking, which leads to increased energy efficiency and prolonged the vehicle's range. Steady performance under a load range and input scenario is ensured by advanced control techniques like PWM and feedback control loop. For using wide-band gap semiconductor devices to enhance the systems performance and efficiency. The readings of Buck voltage and Boost voltage taken from the prototype and also analysed by Matlab Simulation. The buck, boost and voltage ripple will be minimized by the Matlab Simulink. There by increase the Efficiency of the system. From this energy efficient we will achieve the SDG 7 of affordable and clean energy.
