Comprehensive Analysis of DC/DC Converters for Electric Vehicles Applications: Topologies and Future Perspectives

Abstract

In order to implement the global sustainable development strategy, reduce the burden of traditional fuel vehicles on the environment, and at the same time, due to the increasing oil prices, more and more people are reluctant to use fuel vehicles, the global automobile industry. The centre of gravity has gradually shifted from traditional industrial energy vehicles to electric vehicles. As an integral part of the electric vehicle powertrain, the DC/DC converter has the important function of supplying power to the power steering system, air conditioning and other auxiliary equipment.This paper describes in detail the DC/DC converters that provide power for electric vehicles, describes in detail the different types of DC/DC converters as well as the different topologies, and analyses the characteristics of each topology and the method of providing power to the circuit by drawing the circuit of the different topologies. Next, the advantages and disadvantages of various topologies are compared, and improvement methods and future prospects are proposed for the shortcomings of different topologies.
