I have been reading about the concept of a flyback transformers and converters, which has led to various misunderstandings concerning the basic operation of a transformer.
Firstly, dc current don't induce voltage in the secondary windings of any transformer. But in a flyback converter, I read that when the switch is ON, current will build up in the primary winding, and a diode that was added in the secondary winding will prevent current flowing in the secondary winding, until the switch is open or OFF.
Same with a RCC converter.When the transistor turns ON, current will be induced in the auxillary winding.How does this happen?
So can a dc or a short constant current induce voltage in another winding of a transformer?
