| Prof. Chung consults on electronic products, such as a centralized heating system for diving suits, pager systems, and EMC problems and solutions. He was the founding chairman of the Executive Committee of the Sir Edward Youde Scholars Association from 1991 to 1993. He is presently the chairman of the Council of the Sir Edward Youde Scholars Association. The main objective of this Association is to promote education and social awareness in Hong Kong. He is also chairman of the subject committee of the Hong Kong Examination Authority concerned with the examination syllabus for the Hong Kong Advanced Supplementary Level Examination. Prof. Chung has also been appointed as chairman of the Technical Committee on Power Systems and Power Electronic Circuits of IEEE Circuits and System Society. He is currently the Associate Editor of the IEEE Transactions on Circuits and Systems, Part I. He is also the reviewer for many leading international journals, such as the IEEE Transactions on Circuits and Systems, IEEE Transactions on Industrial Electronics, IEEE Transactions on Power Electronics, and IFAC Automatica, etc. He is a panel member of the Government Disciplinary Tribunal Panel under the Electricity Ordinance. |
