  DESIGN FEATURES Phase-Shift Full-Bridge Controller
  Enables Efficient, Isolated Power
  Conversion for High Power Applications
  by John Bazinet Introduction
  The distributed power supply systems of large data processing and
  communications equipment use isolated, high power converters to
  generate intermediate bus distribution voltages and lower voltages for
  CPU, mass storage and I/O circuitry.
  Power supply isolation is necessary
  for regulatory agency requirements,
  shielding of sensitive circuitry and
  ground loop elimination. Unfortunately, adding isolation increases
