Dave,
SCRs are used throughout the sub industry for motor controllers on DC 120V(mostly) propulsion systems. It ain't news.

Strange they would use SCRs. I guess it's because motor control was beingused in subs before the FET.

I found this in the electric car club too. Most people had chopper circuitsusing SCRs, I couldn't understand why as the resistance and voltage drop isgreater than a FET.
