The global shift towards the engineering of efficient and manufacturable electric drive vehicle propulsion systems will result in new challenges in meeting vehicle EMC requirements in order to assure customer satisfaction, meet legal requirements, or support mission performance goals. Much of the existing methods to address EMC of motor drives (primarily conducted and radiated emissions) are based upon “legacy” low voltage components and systems. The high voltage (typically 300 to 600 volts) and high current (hundreds of amps peak demand) in vehicle propulsion systems will require new analysis approaches, test methods, and effective use of simulation/modeling. This tutorial will discuss the development of electric motors from “small scale” to large drive motors, the mechanical constraints of motor EMC compliance, systems integration methods of today, and possible solutions for the future.

This presentation will discuss how to identify the type of measurements and parameters needed to measure common and differential mode response of a multiple line EMI filter. Additionally, the methods discussed will look at an automotive low power example and then discuss the challenges in hybrid vehicles.
