Background
In Electric Vehicles (EVs), the Electromagnetic Interference (EMI) from the electric propulsion system must be kept below limits to meet legal requirement and to ensure full function. To reduce the EMI from the power electronic devices, filters with bulky capacitors and inductors are used that consume quite a lot of space and are costly. One of the most critical paths generating EMI in an electric drive is the drive shaft of the electric motor, where common-mode current can flow through the bearings of the transmission.
Multilevel inverters have been studied as candidates for future automotive electric drives, due to their superior harmonic performance, which can also result in much lower EMI.
Scope
The objective of the thesis work is to investigate the common-mode voltage at the neutral point of the electric motor when a three-level NPC inverter is used for driving it. The impact of utilizing specially designed gate drivers for this inverter type, previously developed in other projects, will be investigated.
