"textContent": "A switch mode control circuit, comprising a battery link configured to connect to a battery, a capacitor link configured to connect to a capacitor, and a pre-charge circuit connected in series between the battery link and the capacitor link configured to limit inrush current to the capacitor during initial power connection. The pre-charge circuit includes a switching mechanism configured to alternate between an open state and a closed state, a shunt resistor to monitor the current, and a controller operatively coupled to the switching mechanism configured to control a duty cycle of the switching mechanism. The controller dynamically adjusts the duty cycle of the switching mechanism by intermittently closing the switching mechanism until a predetermined voltage is achieved, and upon achieving the predetermined voltage, the controller maintains the switch in the closed state to enable continuous direct current flow from the battery to the capacitor.",
