Default soft start for powerhead

Hi,

Rather than digging in to the equations, lets get some trends.

1) Using a Step response to turn on the power supply. In this case, the current will overshoot and have exponential decay function from its peak current.

2) Using a Ramp response. In this case, the current will be a sort of a step response (not quite...but close). This is what a capacitor or a RC response will do -- which we know that it doesn't work very well.

3) Using a x^2 like/sin function. In this case, the current will change more linearily with time. I am just describing the general shape, but this is what I was referring to as a x^2 function.

Either that...or my wires are really crossed from writing too much.

- Victor.
