All,
I cannot complain about the performance of gate
drive transformers, if they have a primary
inductance as recommended by Jan Wagner:
http://users.tkk.fi/~jwagner/tesla/SSTC/general-sstc-notes-gatedrv.htm
50kHz-100kHz 2.0 - 4.0 mH
100kHz-300kHz 0.5 - 2mH
300kHz-500kHz -> 50µH - 500µH
However, it is the volt-seconds of the
transformer that determines it`s suitability as a gate transformer.
Is there a direct path from inductance to
volt-seconds and if not, how do I calculate the
volt-seconds of a transformer that I have made.
Which core parameters define the volt seconds,
and does the turns count, count .
Also, how does volt-seconds relate to operating
frequency, duty cycle and amplitude of the transformed signal.
TIA, Finn Hammer
