Review on Converters used in Electric Vehicle Drive System

Abstract

Electric vehicles (EVs) are gaining popularity due to their improved performance and environmentally friendly nature. The effectiveness of EVs depends on the successful interface between their energy storage systems and propulsion motor. One of the key components of an EV is the motor converter, which converts the electrical energy stored in the battery into mechanical energy that powers the vehicle's propulsion system. The motor converter used in EV drive system is reviewed. Non- isolated converter for DC/DC conversion and DC/AC converter to drive the motor are stated. Despite their usefulness, EV converters have some drawbacks, large number of components, high current stress, high switching loss, slow dynamic response, and computational complexity. This review examines various EV converter configurations, highlighting their topology, features, components, operation, strengths, and weaknesses.
