Abstract: In one embodiment, a hot swap circuit is disclosed. The hot swap circuit includes a first switch connected to a power input line. The hot swap circuit also includes a first capacitor connected to the first switch that is charged when the first switch is closed. The hot swap circuit further includes a second switch connected to the first switch and the first capacitor. The hot swap circuit additionally includes an input capacitor connected to the second switch and located in parallel with an input line to a power system. When the second switch is closed, the input capacitor is charged.

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.
