“The electromagnetic interference (EMI) of a hybrid electric vehicle traction drive, provided by Ford Motor Company, was investigated in this research. Filtering and shielding, were implemented and used to mitigate the electromagnetic interference dominated by the 3-phase cables and the power cables. These mitigation approaches, filtering and shielding, greatly reduced the interference from the hybrid electric drive that can couple to all other electronic devices in the vehicle, e.g., AM/FM radio, engine and transmission controller, cellular phones, GPS and laptop computers.

The EMI coupling paths and internal resonances of power electronics inverter has also been investigated. The possible coupling paths are proposed and demonstrated experimentally. The primary EMI coupling is found to be the capacitance between the heatsink and collector terminals in the Insulated Gate Bipolar Transistor (IGBT). Resonances due to the assembly and packaging of the power electronics was also shown to contribute to the EMI.

The EMI coupling paths and the effectiveness of the mitigation approaches are discussed in this thesis”--Abstract, page iii.
