Hi,
I need help in the selection of Ferrtie core tranforerm for 800 Watt push pull transformer.
The specs are
Input Voltage:
VDC min 10.5 V
VDC max 21 V
Out put volatge:
180 VDC ( output 800 watt when input voltage is from 10.5 to 14 VDC)
180VDC ( output 350 watt when input voltage is 15 to 21VDC).
Switching frequency 50 KHz .
I want to know the material of core . Can is use PQ 35/35, or PQ 40/40 core for this power level? I am using Kg criteria for the selection of core there is apparent power factor. I need explanation for it.
Is it possible to use two small cores one for each ,primary winding leg?
What should be the rating of power mosfets?
Regards
