[RE-wrenches] Diversion load for AC coupled system

[David Katz]

Larry,
I think you want the PWM controller to start first so the turn on will be smooth.  If the current capacity of the diversion controller is exceeded then you want the relay to switch in the big load.  At that point the diversion controller will back off and pickup the difference.  That is why I suggested the the relay controlled load be 50 to 75% of the pwm diversion load, so that whenever it turns on the pwm controller will be working, too.

David,
Ah..I think I see what you are saying. But, don't you mean .2 volts lower than the diversion load? That way there will only be limited current left for the diversion controller to handle. If it is the other way, what stops full current from flowing through the diversion controller if the .2 volts is not reached? Or is .2 volts two close to worry about that?
