DESCRIPTION:PWM converters have been the workhorse for most power conversio
 n applications today. However\, their bulky magnetics limit further power 
 density improvement. Over the years\, researchers recognized that switched
 -capacitor converters do not need magnetics\, but poor voltage regulation 
 prevents them from wide adoption. Resonant converters have penetrated some
  applications\, but they are not ready to replace the PWM converters for h
 igh-power applications due to their high RMS voltage/current and limited r
 egulation capability.\n\nResearchers in the community have been searching 
 for new solutions with better efficiency\, regulation\, and power density 
 at the confluence of PWM\, resonant\, and switching-capacitor converters.\
 n\nThe UCI (UC Irvine) Power Electronics Laboratory has dedicated its effo
 rt to this search for the last seven years. We have discovered several new
  switched-capacitor converters and resonant switched-capacitor converters.
  Recently\, we made a breakthrough to realize full-range voltage regulatio
 n of resonant switched capacitor converters with one small inductor.\n\nIn
  this speech\, Dr. Smedley will present a general “PWM-like” control m
 ethod for resonant switched-capacitor converters with only a 2X frequency 
 swing and only one small inductor (nano-henry scale without DC bias). This
  new generation of power converters can replace a wide array of convention
 al PWM converters\, dramatically reduce magnetic components\, and eventual
 ly eliminate the bulky magnetics overall in fully integrated power chips.\
