WebThe flyback power stage also eliminates two characteristics which sometimes make the standard inverting buck-boost power stage unattractive, that is the output voltage is opposite in polarity from the input voltage and the power switch requires a floating drive. Besides providing isolation, the coupled inductor secondary 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.
