A control system and power electronic for an electric powertrain implemented on a go-kart

Abstract

This report describes the master thesis project where a 3-phase AC -inverter is designed with software to space vector modulate the output currents. The report outlines a brief background to the project and then goes on to describe the demands that the inverter must ful ll. The controlling software is described both in general and the application speci cs are treated. The hardware solution is described and major component choices are discussed. The complete working inverter was successfully implemented on a go-kart, and the testing veri es that the functionality of the inverter is according to the speci cations. The inverter was not fully tested to the upper limits of 72V and 300V peak current due to lack of testing equipment, though the results are promising for the inverter to be able to handle this. 4
