Power electronics is an enabling technology for numerous modern multi-disciplinary applications. In this seminar, the speaker will describe some of its applications for environmental protection, with special focus on energy saving, reduction of electronic waste and renewable energy. The seminar will begin with a brief introduction of the rapid development of power electronics since 1980’s. Then several recent inventions with global impacts on solar power conversion, standby power reduction, dimmable large-scale lighting system, LED system theory, coreless PCB transformer technology and wireless power transfer technology will be described.

The speaker will also address some promising R&D topics for future power conversion and energy research. These fundamental topics include (i) new low-loss circuits to replace existing diode rectifiers, (ii) new ultra-low-loss recyclable ballast to replace existing electronic ballasts for lighting application, (iii) physical modeling of batteries (actual charge indicator) to cope with the future electric & hybrid vehicle era, (iv) dynamic LED system theory, (v) new wireless charging technology (vi) new voltage stability control technology for smart-grid and (vii) Grid-connected technology for energy recycling.
