Introduction: The advent of electric mobility is changing the conventional mobility techniques and their application in automobiles across all segments. Three wheeler Battery Operated Vehicles (BoVs) are a special category of electric vehicles (EVs) as far as EMC compliance is concerned. The problem mainly lies with the open body design and cost cutting measures being exercised by the manufactures which makes Electromagnetic compatibility (EMC) compliance challenging. Objective: Though it is sometimes possible to resolve EMC malfunctions related to motor power cable, cables & wiring harness etc. using external techniques post design stage, but controller being a closed and typical element makes it difficult to improve against EMC malfunctions using external techniques. This paper would concentrate on the controller design parameters and improvement of the same in terms of Electromagnetic compatibility (EMC) and performance efficiency at the design stage itself. Methodology: This study would concentrate on designing of motor controller for three wheeler EVs, improving and optimizing the EMI/EMC aspects of the design and its performance with the following aspects in mind: 1. Selection of critical…
