My major area of interest is the emerging discipline of power electronics especially as applied to variable speed operation of ac machines. One challenging aspect of research in this area is its multidisciplinary nature. The fundamentals of solid state devices, integrated circuits, control theory, computer simulation, microprocessors, circuit theory and electric machines are all brought into play before a satisfactory design can be realized. A few examples of projects which illustrate the scope of this research are described below.
For the past several years, we have been investigating power conversion system based on resonant current and voltage links. We have been involved in the simulation, hardware design and control philosophy associated with this topology and have published over 30 papers, and received three U.S. patents on this technology.
Another area of considerable interest is the design of machines with unconventional winding configurations and/or geometries which will operate more harmoniously with a solid state frequency converter. For example we are designing three new, unconventional reluctance machines which promise to provide higher power density, lower noise and lower cost than that of other machines. We are also designing a new type of permanent magnet machine which has particular advantages in high speed operation or in applications requiring field weakening (for example in an electric car). Several U.S. patents have been issued. It should be mentioned that these projects require not only design and construction of the machine but also the associated power electronic converter and controller. Hence, the challenges are interesting, multifaceted and firmly embedded in the real world.
