The teaching and research activities in the Power and Energy Area can be mainly divided into four different programs: Electrical Machines and Drives, Power Electronics, Power Systems, and Semiconductor devices. There are several emerging applications such as microgrid, electrification of the transportation sector, renewable energy, wide bandgap devices, marine applications, data centers, LED lighting, wireless power transfer, energy harvesting, energy storage, and nano-satellite. Power Systems research is focused on advancing the state-of-the-art in the areas of analysis, intelligent computational and control, reliability, and monitoring of power systems. Research in Power Electronics, on the other hand, is focused on developing new converter topologies and 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. Some of our faculty members also have a strong interest in the application of computational intelligence to transportation systems. Electrical Machines and Drives research is 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, fault diagnosis, condition monitoring and maintenance of electrical equipment, building and industrial processes energy efficiency enhancement, biomimetic fish propulsion and central pattern generation mechanisms etc.. Semiconductor Devices research is focused on developing high voltage wide bandgap semiconductor devices to raise the system performance and energy efficiency.
Power and Energy System (PES) research area is divided mainly into four categories: (1) Power Electronics, (2) Electrical Machines and Drives, (3) Power System, and (4) Power Semiconductor Devices.
The research group has 9 faculty members working in these areas with nearly 30 PhD students, 12 Masters, and 20 researchers.
The group is involved into interdisciplinary system level research with several industrial collaborators such as Rolls Royce Singapore Pte. Ltd., Infineon Technologies Singapore, Siemens Oil and Gas Solutions, Singapore Technologies Marines, Singapore Technologies Info-Comms., Schlumberger Innovation Center, Singapore, Panasonic Home Appliances, Singapore.
The PES Group faculty members are also actively involved in two of the NRF-CREATE Programs namely: (1) Singapore Berkeley Building Energy Efficiency and Sustainable Technologies (SinBerBEST) and Cambridge Center for Carbon Reduction and Chemical Technologies (C4T). The faculty members have also been active in participating in A*STAR Thematic Research Programs such as Intelligent Energy Distribution Systems (IEDS), Future Green Data Centers, GaN Power Device Technology (MOS-HEMT) on GaN-on-Si for High Voltage (kV) High Power (kW) Applications
The PES group faculty members have been very active in bidding and getting research grants through various governmental agencies such as Energy Innovation Research Program (EIRP), Singapore Maritime Institute (SMI) Research Grants, DRTech Research Grants etc. .
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.
Electrical Machines and Drives research is mainly focused on fault diagnosis and condition monitoring of electrical equipments, 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.
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 are ongoing research topics.
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 application of our research area has a wide range including low-power intelligent sensing nodes, assistive technology, energy harvesting, control and management of electric vehicles connected to the power grids, and integration and control of renewable energy sources.
