SYSTEM FOR LIMITING INRUSH CURRENT IN A BATTERY ENDPOINT
DRIVE
March 25, 2021
Described is a system that includes a solid-state switch in series with a battery and a controller. The system also includes a capacitor coupled between a source and a gate of the solid-state switch and a resistor coupled between the gate of the solid-state switch and ground. The solid-state switch gradually transitions from an open state to a closed state over a time constant of the capacitor and the resistor upon application of power from the battery to the solid-state switch. The system further includes a first switching device that controls the application of power from the battery to the solid-state switch. Additionally, the system includes a second switching device that provides a discharge path of the capacitor upon completion of a task by the controller.
