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
