Abstract

The purpose of this research project is to gain an understanding of the critical role power electronics play in the design and operation of the EV and to provide an adequate explanation of the operation of those power electronics circuits and how the circuits accomplish their purpose. The project covers the power electronics circuits such as the AC-DC converter as well as the DC-DC boost converter and how they operate as well as why these circuits are necessary in the onboard charging operation of the vehicle as well as the offboard charging stations. For the operation of the motors the DC-AC inverter is discussed and the role it plays in controlling the speed and torque of the motors. The report will then briefly touch on the limitations currently facing power electronics in the automotive industry, such as materials and packaging, and the research currently being done to address those limitations. The problems currently facing the electrification of larger vehicles such as pickup trucks and semi-trucks, which include battery weight and high-power charging stations, are also briefly touched on. The report will also include appendices which will provide a more in depth look at the discussed power electronics circuits with LTSpice simulated waveforms and schematics as well as explanation of some more advanced mathematical topics such as the Fourier series and Taylor series. This report also includes appendices that provide the specifications and operation of the various levels of vehicle charging as well as specifications of some of the most popular EVs available.
