HOW TO DESIGN A FEEDBACK LOOP COMPENSATOR FOR A FLYBACK CONVERTER IN FOUR STEPSARTICLEDue to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic topologies — specifically, buck-boost topology. However, unlike buck-boost converters, flyback topologies allow the voltage output to be electrically isolated from the input power supply. This feature i...
