Description

Organizer:  

Professor Huai Wang, hwa@et.aau.dk Aalborg University, Denmark 

Lecturers:  

Professor Huai Wang, Assistant Professor Haoran Wang (Aalborg University) 
Postdoc Yanfeng Shen (University of Cambridge) 

ECTS:  4 

Description:   

The course was initiated in 2020 aiming to lay a solid foundation in power electronics could be beneficial to them independent of which power electronic topics they are working on, which provides also a wider scope of power electronics besides their specific research topics. It will have in-depth introduction of circuit theories, modeling methods, and hands-on prototyping of power electronic converters. The emphasis is on those aspects that are generic and not limited to specific applications.  Moreover, a design case study will be used during the entire course for illustrating how to implement a converter prototype step-by-step, from component sizing, circuit design, control, simulation, prototyping, and testing.  PCB assemblies will be available for the participants to perform laboratory testing.   

  • Day 1: Power electronic circuit theories + design case (Lecturer: Huai Wang, 8:30-16:30) 

It will cover the topics: duality in time and circuit elements, state-plane switching trajectories; inductor-capacitor based switching circuits, switched-capacitor circuits, switched-inductor circuits, zero-ripple techniques, interleaved techniques, extra element theorem, circuit operation-mode analysis, etc. 

  • Day 2: Power electronic modeling and control methods + design case (Lecturer: Haoran Wang and Yanfeng Shen, 8:30-16:30) 

It will cover the topics: how a “switch” can be removed for converter modeling; origins of time-domain and frequency-domain modeling methods and its limitations; basic ideas of time-domain control methods for power electronic converters and its advantages and limitations; most widely used frequency-domain control methods for power electronic converters; what are the common and different aspects in modeling and simulation of Si, SiC and GaN devices.    

  • Day 3: Magnetic component modeling and design + design case (Lecturer: Huai Wang, 8:30-16:30) 

It will cover the topics: magnetic diffusion, core losses, winding losses, high-frequency magnetics, integrated magnetics, and magnetic circuit representation, design considerations, etc. 

  • Day 4: Power electronic converter prototyping and testing (Lecturer: Haoran Wang and Yanfeng Shen, 8:30-16:00) 

This is a continuation of the design case for actual prototype implementation and testing. It will cover the topics: PCB design techniques and considerations; participants make their own magnetics and be given PCB assemblies; run tests in the lab) 

Prerequisites:  

A basic understanding of power electronic components, topologies, and control methods are necessary, the participants are supposed to have already attended a master-level power electronic course or equivalent.    

Form of evaluation: 

Converter case study design and testing report.
