They have lower, forward losses, and coupled with a feedback circuit, provides voltage regulation.

Are there any "off the shelf" 240v 100amp synchronous rectifiers?

If a simple oscillator would control PWM one could build a simple dial in your current device with an ammeter a sr and a variable oscillator.
