Problem with motor drive IGBTs
Problem with motor drive IGBTs
(OP)
Hi,
I was wondering if anyone knows the details of measruing the capacitance of an insulated gate bipolar transistor (IGBT). Specifically, the circuit shown in Figure 23c of
http://www.irf.com/technical-info/appnotes/an-983.pdf
shows a 1:10 transformer. Does anyone know what the transformer is for? Also, there are two ground connections which appear to be different. Any clarification on this would be appreciated very much.





RE: Problem with motor drive IGBTs
As to the ground in question, I suspect that is a typo. Not uncommon in app. notes and datasheets.
