دانلود Resonant Switched-Capacitor Voltage Regulator With Ideal Transient Response

Abstract

A new, small and efficient voltage regulator, realized using a resonant switched capacitor converter technology, is introduced. Voltage regulation is implemented by means of simple digital pulse density modulation.  It  displays  an  ideal  transient  response  with  a zero-order nature to all disturbance types. The newly developed  topology  acts  as  a  gyrator  with  a  wide  range  of voltage  conversion  ratios  (below  as  well  as  above  unity) with constant efficiency characteristics for the entire operation  range.  The  operation  of  the  voltage  regulator  is verified  on  a  20W  experimental  prototype,  demonstrating ideal transient recovery without over/under-shoots in response to load and line transients. Simple design guidelines  for  the  voltage  regulation  system  are  provided and verified by experiments.
