Power and Energy


The teaching and research activities can be categorized into four main themes: Electrical Machines and Drives, Power Electronics, Power Systems, and Semiconductor devices. The application of our research area has a wide range including smart grid technologies, renewable integration, energy harvesting, control and management of electric vehicles connected to the power grids, low-power intelligent sensing nodes, and assistive technology. Meanwhile, Semiconductor Devices research is focused on developing high voltage (650 V, 1200 V) wide bandgap semiconductor devices to raise the system performance and energy efficiency, via the high quality switching devices operating under high-frequency energy conversion. This includes their design, modelling, fabrication processes, device prototyping, gate drives, protection circuits and overall integration. Such devices are suitable for renewable energy market, electric vehicles and smart power grid in the distribution level. The group is involved into interdisciplinary system level research with several industrial collaborators and various governmental agencies.


 

Research Focus


 

Power Electronics


Power Electronics research is mainly focused on analyzing, designing, and developing novel power converter topologies and innovative modulation techniques for the given applications. Ongoing research mainly focusses on modern and emerging applications such as microgrid, nano-satellite, marine, renewable energy, energy storage, transportation, data centers, UPS, LED lighting, active filtering, etc. It is also focused on advanced nonlinear control techniques to address the fundamental problems in the area of motor drives, power electronic converters, active filters, intelligent power semiconductor devices, and lightning protective devices.

Power Systems


Power Systems research is focused on advancing the state-of-the-art in the areas of analysis, intelligent control, reliability, and monitoring of power systems. Developing optimization techniques, intelligent computation tools, and reliability analysis,renewable energy integration, renewable power output forecasting, electricity price forecasting, electric vehicle integration, energy storage systems integration are ongoing research topics.

Machines & Drives


Electrical Machines and Drives research is mainly focused on fault diagnosis and condition monitoring of electrical equipment, i.e., transformer, motor, generator, converter, etc. Advanced control of medium voltage high power industrial AC drives and advanced nonlinear control techniques to address fundamental problems in the area of motor drives is another focus of current research.It is also focused on control of high power AC drives, torque ripple minimization of AC Drives such as Permanent Magnet Synchronous Motor (PMSM) and Switched Reluctance Motor (SRM) Drives, high-performance control of electric drives, building and industrial processes energy efficiency enhancement, biomimetic fish propulsion and central pattern generation mechanisms etc.
