WebFlyback converters are defined as power converters, which convert AC to DC with galvanic isolation between the inputs and outputs. It stores the energy when the current flowing through the circuit and releases the energy when the power is removed.

The flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage. There are three common ways to generate this voltage: 1.
