Paul - you mentioned using a combination of the 4011 and 2010 for the inverter functions and boost functions.

I know you're not a fan of the surface mount stuff, but have you looked into the 5015's or 6015's?

According to the spec sheets, they have motor control PWM channels. Have you looked at whether it's possible to run 6 channels for standard 3 phase and **completely independantly** 2 channels for the boost control?

Or would it be at least possible to run 6 channels as 3 phase with 2 channels running a different PWM, as necessary? Perhaps sharing the same switching frequency...

Any idea of how independantly these channels can be operated?

Thanks a bunch,
