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. Use an optocoupler on the secondary circuitry to send a signal to the controller.

WebSingle stage high power factor flyback converters must draw predominately sine-shaped current to maintain high power factor. This means the converter must process power in a sine-squared manner due to the product of sine wave voltage times sine wave current. An LED load draws a nearly constant average power from the power supply output capacitor.
