Description

The emphasis of this course is to give a complete and clear picture on EMI issues and mitigation methodologies. Systematic designing of passive EMI filters for differential mode (DM) and common mode (CM) noises in single-phase and three-phase systems will be provided. Printed circuit board (PCB) design criteria, passive and active components parasitic and shielding approaches in reducing near-field couplings will be covered as well. Furthermore, time and frequency domain modeling of conducted low and high frequency emission noises through developing equivalent circuit models of power electronics converters in order to reduce the analysis complexity and prevent from conventional trial and error design approach will be addressed. This course will also focus on new challenges within the new frequency band of 2-150 kHz in power electronic based power systems. The course content is combined with real-world application examples and demonstration.

In the first day the course will focus on basics of harmonics generated by switching, EMI issues in PWM converters, components parasitic, measurement requirement, interference mechanisms, filtering component and strategy. In the second day there will be more focus on advanced topics such as magnetic coupling, EMI prediction, Shielding and new standard requirements. The second day will be supported with industrial examples and real-world design experience regarding different aspects of EMI/EMC in power electronics.

Prerequisites

This course is intended for intermediate and advanced researchers and engineers in the field of power electronics and its applications, for EMC specialists and advanced university students exploring new harmonics and EMI challenges in power electronics-based power system and WBG-based power electronic systems. General knowledge in power electronics converters operation modes, passive components and basic control theory are preferred. Course exercises and mini-projects will be performed on MATLAB/PLECS software platform.

1. Pre-reading the shared materials
2. Power Electronics
3. Basic understanding of power electronics control

Form of evaluation

The participants will work on mini-projects in the final 1-day lecture. The mini-projects are defined based on a real application design and will be assigned to group of four people. Groups will compare and deeply discuss their design method and choices and present their results in presentation form to the class.

1. Mini-projects
2. Power point presentation

Price

6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry.
