Welcome to Power Electronics – from Fundamentals to Advanced Topics


Description:

Our existing courses in the area of power electronics at the Department of Energy Technology focus on either applications or a specific technical topic. By collecting the feedbacks from many PhD students in power electronics internally and externally, a course that can 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. This newly initiated course 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:

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
