Question for Mike;
I see the TS100 on ebay under several brands - Uy Chan, Sainsmart, Ykey, Usmile (really), Novellife, etc. Are they all about the same or is there one you prefer?

I think the problem with IGBT's is that, while they will turn off under load, they don't do it very well unless you drive the gate down quickly. The 40N120L3 in my PV hybrid water heater has a...

Some of the literature I read says IGBT turn-off time (and thus the frequency) depends on the driver's ability to pull the gate down quickly. This is because of gate-emitter (I think it was the...
