Hello,
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
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.
