inrush current limiting for 150A at 45V
inrush current limiting for 150A at 45V
(OP)
Does anyone have a suggestion on an elegant solution for limiting the inrush current going through a diode pack that is rectifying a 45V 150A current. The caps are very big and the initial draw is forcing me to rate the diodes at much higher than the nominal draw. If I can somehow limit the inrush, I won't have to worry about burning diodes. I am thinking of using an inductive load in series with the diodes. Any thoughts?

I've seen this done in two ways;
A timing relay that shunt the resistor after a fixed period and having the relay in the DC curcuit after the filter cap. When the cap is charged, the relay operates, again shunting that resistor.
