Dear All,
I am studying transformers in power supply (AC-DC converter). On the first picture, there is one transformer having 3 windings: the primary (1) that takes high voltage input and driven by MOSFET, the secondary (2) that gives low voltage output which will be rectified and become the supply output, the auxiliary (3) that supplies low voltages to control IC.
If I separate the auxiliary winding into the 2nd transformer (2nd picture). Would the start up time measured from when we apply the AC input and when the aux. voltage becomes stable be faster than the 1st picture?
I would appreciate if you provide me names of references I can read further.
Sincerely,
BlackMelon
