RCC is pleased to announce the Science & Industry Seminar by José A. Cobos, founder of “Centro de Electrónica Industrial, CEI-UPM”, a University research center leading a strong industrial program in power electronics and digital systems.
Power Electronics is a key enabler for Energy efficiency. The talk includes an overview of different techniques to save energy. Power supplies can no longer be designed as independent building blocks, since Energy is required ubiquitously. It is becoming a seamless functionality of the system itself.
In RF amplifiers, power consumption is reduced by appropriate modulation of their supply voltage. In microprocessors and digital systems, dynamic voltage scaling, increased granularity and voltage stacking increase battery life. Rippled based control reduces capacitance requirements and facilitates integration in “Power Supplies on chip” (PwrSoC). In modern Aircrafts, rectifiers & DC-DC converters generating high voltage bus (270Vdc) reduce weight and fuel consumption. Lithium batteries are being extensively used in electric vehicles and domestic and industrial PV panels. The recent improvements in power switches (GaN and SiC) turn the focus again in the design and optimization of high frequency magnetic components. A holistic optimization approach including all these techniques in a top-down approach is needed for maximum energy savings. Finally, the participation of the team CEI@UPM in the “Little Box Challenge” (Google and IEEE-PELS) will be discussed.
The talk will start with some reflections about professional trajectories and mobility from the speaker’s perspective, belonging to a Spanish R&D Center with a strong Industrial Program (CEI-UPM), on sabbatical this year at Harvard (RCC Fellow) and UC Berkeley (Fulbright).
