Scr gate transformers, any good?

Andypairo · 23rd May 2004, 11:55 AM

Hello,
I've come across a number of pulse transformers used for driving SCR gates in motor drives.
I was wondering if they could be good for SPDIF isolation... the windings show a fairly similar DCR, around 1.5 Ohm (one is a bit higher tough), while measuring the inductance I got 10 mH for one winding and about 20 mH for the other.
I took a shot of it...

Any suggestion?

Cheers

Andrea

Hi,

found your question looking for suitable gate pulse transformers. Seen them used in radar modulators, presumably to give good isolation from driver to HV on anode. Did you find a suitable spare; looking to buy some myself.

cheers..

Nick
