Flyback auxiliary winding

WebNov 25, 2024 · As you may know, the flyback transformer stores energy in its inductance when the transistor (switch) is on and inductive current builds in the primary, and then transfers that energy to the other windings by transformer action when the transistor turns off.

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.
