I need to learn a bit more about IGBT dimmers in the 10-100kW range. I have done a lot of work with IGBTs generating AC from a DC buss, and a bit of work with SCR/Triac dimmers, but have never used IGBTs in dimmer circuits. Does anyone here have experience with them?
My initial impression is that I will be able to reduce harmonics and that the price will be quite a bit higher, but what about power dissipation and product weight (smaller chokes)?
Wild idea: could this possibly be an application suitable for a GTO (Gate turn-off Thyristor)?
