Abstract
An adaptive pre-charge control circuit includes include a high-voltage switch and a control circuit. The high-voltage switch controls the flow of current between an electric battery and a DC link capacitor, the electric battery to supply power to an electric vehicle. The DC link capacitor is made up of a sum of individual input capacitors of multiple subunits within an electric vehicle. The control circuit sends a PWM signal to the high-voltage switch based on a difference between an electric battery voltage and a DC link capacitor voltage.
