I need to know how to properly select the right value filter capacitor and how many to put in parallel for a PWM motor controller I am building. I know how to select capacitor values for 120 hertz full wave rectification of AC ripple voltage and 60 hertz half wave rectification ripple voltage, but this design has DC going in and it will only have dips when the MOSFET switches ON as well as how much load is placed upon the motor's shaft when the MOSFET is ON thereby causing more current draw. So how would I properly select the capacitor value to account for these transient voltage dips? I do have some Panasonic FM series FM1V152 1500uF low ESR capacitors, but I think these may be overkill...
