Monday Prof. Philip T. Krein Power Electronics and the New Energy
Revolution: The How of Alternative and Sustainable Energy in a Transitioning
World This presentation illustrates the new
electrical energy revolution - the twenty-first century revolution that is
completely changing the original twentieth century electrification revolution.
With present concerns about energy costs and depletion of fossil fuels,
technologies that support sustainable energy processes are becoming critical.
It is shown how that power electronics, the processing of electrical energy
with electronic circuits, is the driver behind this revolution. Modern portable
devices, new energy resources, the fundamental changes occurring in
automobiles, and many other areas have power electronics as a critical enabling
technology. These innovations are the basis for alternative and sustainable
energy technologies for the future. The tasks require nonlinear switching
circuits, the core technology of power electronics. Examples include electronic
motor drives, dc-dc converters, solar energy power conditioning circuits,
"digital power," electric and hybrid automobiles, single-chip power
converters, high-efficiency power supplies, special semiconductor devices, and
even applications to audio amplifiers. Emphasis is on the urgent need for
engineers familiar with the challenges and design tools of power electronics to
help move into a new energy era. Biography: Philip T. Krein is the Grainger Endowed
