That confused me.

I have a few years under my belt in industrial electrical work, too, and I've always thought that a rotary converter was more efficient, as it delivers a waveshape closer to 3-phase due to the generator effect of the idle motor.

I'd appreciate it if you would elucidate me on the engineering, as I have apparently been misguided for a long time!
