Hello,
I need to make a controlled load, which is supposed to drain specific amount of current (0-30A), according to specific timing (minimum step is 10ms). the power sourse is a chemical battery - 30v DC
I was thinking to implement some sort of step up circuit, with PWM modulation, controlled by PC or microcontroller (closed loop).
hower i'm having trouble making the circuit responsive enough (the 10 ms pulse requirement), while keeping the ripples low enough.
Also I don't know how to get the whole desired range (0 - 20A)
Anyone can help me with the concept?
thanks ahead,
Michael.
