Abstract
In one embodiment, a hot swap circuit is disclosed. The hot swap circuit includes a capacitor in parallel with an input line to a power system. The hot swap circuit also includes a switch in parallel with the input line to the power system and coupled to the capacitor. The hot swap circuit further includes circuitry configured to pre-charge the capacitor to a first voltage while the switch is open. The switch is operable to cause the capacitor to be charged from the first voltage to a second voltage when the switch is closed.
