An Upgraded Bidirectional T-type Multilevel Inverter for Electric Vehicle Applications

This study offers a unique two directional multi-level converter architecture for use in electrical transports vehicle application. It has a multilayer DC to DC conversion with a capacitor voltage balancing function for direct current links. The multi-DC-DC converter is two directional, which is a need in electric vehicles. On comparison with traditional setups, the suggested one uses two additional power relays and a capacitance through balancing the voltage of a T three side type MLI capacitance over the course of a whole drive loop or visualise error circumstances. Furthermore, the heavy electrolytic condenser employed in T three-sided type of MLI are substituted with extended life, a more reliable film capacitance in the proposed arrangement because of the repeated cycle-bicycle voltage balancing CCnn and CCpp. The converter's size and weight are reduced by 20% as a result of this. This frees up additional room in the chassis' space envelope for the electric vehicle battery, allowing it to grow in size. Using a Mat-lab/Simulink simulation model, the proposed configuration is evaluated and confirmed. To offer proof of concept, a protype is being created.
