What is the most used topologies for computer power supplies nowadays? I am asking about the ones in the 400-500W range. I assume most are switching power supplies, but what topology of switching power supply is used mostly?
Also, do they regulate one channel (like 5V line) only in their PWM control, and the other secondaries just track that, or do they regulate each channel seperately..? 5V, 12V, 3.3V..etc seperatley regulated?
Any schematics/articles/websites to describe how those supplies are built would be very helpful.
I have a book about switching power supplies, but it lists almost 30+ topologies in general, without saying which is mainly used in PC industry...
Thanks in advance....
