Abstract
This chapter discusses the application and design of power electronics in automobiles. The modern automobile has an extensive electrical system consisting of a large number of electrical, electromechanical, and electronic loads that are central to vehicle operation, passenger safety, and comfort. Power electronics is playing an increasingly important role in automotive electrical systems–conditioning the power generated by the alternator, processing it appropriately for the vehicle electrical loads, and controlling the operation of these loads. It is being used to enhance the output power capability and efficiency of the electrical power generation components. Power electronics is also an enabling technology for a wide range of new and improved functions that enhancevehicle performance, safety, and functionality. The design of automotive power electronic systems is strongly influenced by the challenging electrical and environmental conditions found in automobiles. Important factors include the static and transient voltage ranges, electromagnetic interference and compatibility requirements, and temperature and other environmental conditions. Some of the most important design considerations for automotive power electronics are also addressed
