A flyback converter is composed of a flyback transformer, switch, rectifier and filter and the control mechanism to drive the switch and provide regulation. It is a low part count switching converter and relatively easy to make or design. A flyback converter is an isolated switching converter that can be a step down or step up configuration. Most cell phone, tablets and laptop chargers are made from flyback converter. Following topics will discuss how flyback converter works.
For small power applications like on board power sources, linear power supply is often used due to its simplicity and low cost. However, when the need for high power density designs arises, linear power supply simply disappears in the picture. It is because linear power supply is very less efficient. Switch mode power supply comes in place. Switch mode powerContinue reading
