Design of Buck Converter With Control System for Electric Vehicle Using SiC Device With Thermal Loss Model

Abstract

In today’s day and age, power electronic components are found in all areas of an electric vehicle, from power train to motors and from battery to ancillary loads. Power converters are used to optimize energy management in an automobile. While doing the electrical design of a power converter, the thermal aspects are usually neglected causing a vast difference in the simulation and real-life application. This paper aims to show how taking thermal characteristics into account for a power converter is beneficial and how it influences the results.
