Abstract
A dual-switch flyback converter in which the output current, in operating regions where a constant output current is required, can be regulated from the primary side. The output current is regulated constantly regardless of the input and output voltages by compensating the peak current in the primary winding with the average current in the clamping diode, or the conduction duration of the clamping diode.
