Description

This 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 Subham Sahoo, 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 Yi Zhang, 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.
