Design and Simulation of Non-isolated Bidirectional DC-DC Converter for Vehicle Application

The three most important parts of an automobile's electrical system are the starter motor, the generator, and the battery. These parts are needed for the engine to start, run easily, and power components like windows, lights, air conditioning, and all other electrical devices. All the electrical parts of a vehicle are powered by a battery through relays and switches. The engine powers the alternator, which is responsible for turning mechanical energy into electrical energy. To properly convert electricity between the 12V (LV) side and 24V (HV) side, a non-isolated bidirectional DC-DC converter is needed. As a result, power may be sent to all the electronic parts more effectively. To meet these requirements, this project involves the designing and simulation of a non-isolated bidirectional DC-DC converter. The results of the implementation show how well the converter keeps the flow of power constant and gives the electrical system its best performance. This bidirectional converter gives users several benefits, such as improved battery performance, longer battery life, and better use of available power sources.
