Description: The course was initiated in 2021 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 (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 (Lecturer: Subham Sahoo, Ariya Sangwongwanich, 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. Examples in DC-DC converters and inverters will be used.
Day 3: Power electronic converter prototyping and testing (Lecturer: Zhongting Tang, and Yi Zhang, Subham Sahoo, and Ariya Sangwongwanich, 8:30-16:00)
This is a 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)
Day 4: Practical power electronic components (Lecturer: Huai Wang, and Yi Zhang, 8:30-16:00)
It will cover the topics: power semiconductor modeling and simulation methods, magnetic diffusion, core losses, winding losses, high-frequency magnetics, integrated magnetics, and magnetic circuit representation, design considerations, etc.
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.
