- This discussion pertains only to poorly designed AMPS. There should be no voltage sag and the amps should be ccs at 1.5 kw out (in the US). If digital modes are contemplated, 5 to 10 KW amps in class

- This is easy with a switcher. Switching designs include PWM controller chips designed for that purpose. They have various external inputs for voltage control, current limit, etc. It takes a few small
