Introduction
Today’s high voltage applications—such as automotive, industrial and FireWire peripherals—place increasing demands on power supplies. They must provide high power, high efficiency and low noise, in a small space and over an ever-widening range of operational input voltages. Many high voltage DC/DC converter solutions can meet some of these conditions at high input voltages but they are unable to maintain high efficiencies ...
