Abstract

In many applications it is needed to have an efficient regulated power supply with isolated output. The traditional approach is to use a pulse transformer to transfer energy from the primary to the secondary winding with feedback from the output of the power supply, implemented via an optocoupler or another transformer, to control the driving circuit of the primary to keep the output voltage in a predefined range.
