적응형 프리-차지(pre-charge) 제어 회로는 고-전압 스위치 및 제어 회로를 포함한다. 상기 고-전압 스위치는 전기 차량에 전력을 공급하는, 전기 배터리 및 DC 링크 커패시터 사이의 전류의 흐름을 제어한다. 상기 DC 링크 커패시터는 전기 차량 내 다수의 서브 유닛들의 개별 입력 커패시터들의 합으로 이루어진다. 상기 제어 회로는 전기 배터리 전압과 DC 링크 커패시터 전압의 차이에 기초하여 고-전압 스위치에 PWM 신호를 보낸다.

    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.
