Innovative Technology Series (Workshop 6)

Workshop 6:   A half-day workshop in Advanced Power Electronics Technologies

Topic : The Role of Circuits and Systems Theory in Power Electronics: Methods, Applications and Case Studies

Much of the power electronics discipline has been built upon the application of circuits and systems theory which spans across various
aspects of fundamental circuit, control and system theory. However, in the process of developing solutions for new applications, the
proper use of circuits and systems theory has not always been borne in mind, leading to unnecessary repetition and reinvention of
concepts that would otherwise be reached directly if the approach taken had thoroughly considered the existing knowledge in circuits
and systems. In this lecture, the role of circuits and systems will be revisited and examples will be shown to illustrate how proper
application of existing circuits and systems theory would conveniently lead to important observations and conclusions that would
save re-investigation or expedite understanding of the problems. Specific applications of current interest to be tentatively covered in
this short tutorial include LED driving, power factor correction, parallel-connected converters, inductive power transfer, etc. In each
application, the basic circuit theory relevant to analysis and design of the system in question will be expounded and its proper use will
be shown to be crucial in gaining significant improvement in understanding the key properties and systematic generation of design
solutions. It will be shown that even the basic principles of circuit duality and Kirchhoff’s laws are not always appropriately exploited
in power electronics, let alone proper application of these principles that would lead to systematic design approaches for LED driving
and interconnection of power converters. Furthermore, use of power flow graphs and consideration of effect of parameter changes in
conventional resonant circuits would be discussed, and their applications leading to systematic understanding of the design problems
and classification of solution approaches for power factor correction circuits and inductive power transfer circuits will be illustrated.

About  ITS Workshop

Jointly organized by the Department of Electronic and Information Engineering, The Hong Kong Polytechnic University (PolyU EIE), Hong Kong Applied Science and Technology Research Institute (ASTRI), and Hong Kong Science and Technology Park (HKSTP), the Innovative Technology Series (ITS) seeks to keep the industry and the community abreast of the current and emerging technologies in electronic and information engineering. The ITS will be delivered in a series of 12 structural professional training workshops covering different topics of current and upcoming technologies as well as the latest research results. Presenters of the training workshops will be the professors of PolyU EIE and research project leaders of ASTRI. Overseas experts may also join the training workshops to share their experience with local industry and community.
