Interesting that you should mention that.... A bit of a tangent here, but I've been thinking lately, due to the nature of IGBTs one could design a dimmer system that actively remains in complete balance across all three phase legs no matter what the scene. To do so, the unit would use a master 3 phase power supply that produced a + / G / - buss output (much like a power amp.) Each IGBT PWM sign wave dimmer would the operate off the rails. No matter what circuits were loaded, the draw would be balanced on all three phase legs perfectly. I wonder if anyone is working on this?
end tangent.
We could do that. However, we'd like to be heading in the other direction, cost-wise, in order to drive down the cost of IGBT or MOSFET sine wave dimmers.
