Power Electronics activities at CEI are related to Power Supply Systems of any nature, ranging from low power (5mW)
cochlear implants to high power (100kW) X-ray applications. However, most of the activities deal with DC-DC, AC-DC or
DC-AC conversion in the range of tens or hundreds of Watts.
The traditional research areas of the centre are: power supply systems, power management; energy efficiency, nonlinear
control, modelling and simulation of magnetic components, converters and systems
This research has allowed the design of high efficiency power supplies for telecommunications, avionics, medical,
military and automotive industries.
The incorporation of nonlinear control techniques, multi-phase converters and digital control have improved
substantially the benefits of the converters and opened the door to new applications such as RF amplifiers. Recently,
we are working with wide bandgap devices, both GaN and SiC, the development of models for EMI / EMC and some
renewable energy systems.
• Power Conversion: DC-DC converters, inverters and power factor correction
• Energy efficiency and high power density
• Device modeling, converters and power electronics
• Control techniques: fast dynamic response, nonlinear control, digital control
• WBG semiconductors, GaN and SiC for high frequency converter switching
• Modeling filters EMI / EMC for converters and systems
• Autonomous systems, battery chargers, solar power micro-inverters, converters for electric vehicles and energy
The funding scheme of this area is based on public national funds, mainly from Plan Nacional (MCInn), CENIT and EU
funds and also with direct contract with the industry, cooperating with companies as ABB, Agere Systems, Airbus,
Alcatel, Ansoft, Ansys, Astrium-Crisa, Boeing, Cochlear, EADS, Enpirion, Fagor, General Electric, Indra, Intel, Philips
Hearing Implants, Premo, Sedecal, Sener, Siemens, SISC and Tecnobit.
