I have been doing lots of research and purchasing components to build a high power switchmode power supply, first part i have decided to tackle is the high frequency power transformer, i am using an EE80 core, in the research i have done primary turns are calculated as follows:
Primary Turns = (voltage * 10^8) / (4 * Frequency(hz) * Max Flux Density(gauss) * Effective Core Area(cm^2)
Voltage = 330v
Frequency = 100khz
Max Flux Density of the EE80 core i chose = 5000gauss
Effective Core Area = 4.06cm^2
From my calculations and more research i will need 4 primary turns if i use a full bridge set up, or 8 primary turns for a half bridge setup, is this correct? i am still learning and would like to check my work as i go
EDIT: I caught my mistake, i used the Bsat(flux saturation) instead of Bmax(max flux density) did some more research and found that 1000 gauss is acceptable for the frequency i will be using, so i will need 20 turns for a full bridge setup, or 40 turns for a half bridge setup, correct?
EDIT EDIT: These are the cores i will be using: http://www.ebay.com/itm/271418168459?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
