EMC Issues in Hybrid and Electric-Propulsion Vehicles at the 2009 IEEE EMC Symposium

Chair: Mark Steffka, General Motors and University of Michigan, Michigan, U.S.A.
Co-Chair: James Muccioli, Jastech EMC Consulting, LLC, Michigan, U.S.A.

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.

Design, Engineering, and Manufacturing of Motors for Electric Vehicle Applications (PDF)

M. A. Steffka, University of Michigan-Dearborn, Dearborn, Michigan, U.S.A.

EMC System Engineering of the Hybrid Vehicle Electric Motor and Battery Pack (PDF)

J. Muccioli; and D. Sanders, - Jastech EMC Consulting LLC, Farmington Hills, Michigan, U.S.A.

This presentation looks at the current and future EMC challenges of hybrid vehicle electric motors and battery packs. The focus will take a system engineering approach to identify requirements, design direction, and cost.

Evaluating Multi-Line EMI Filters for Common Mode & Differential Mode (PDF)

D. Sanders; and J. Muccioli, - Jastech EMC Consulting LLC, Farmington Hills, Michigan, U.S.A.

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.

Modeling and Simulation of Powertrains for Electric and Hybrid Vehicles (PDF)
