Beschreibung
Zusammenfassung:	The present subject matter discloses a pre-charging system in a vehicle. The present subject matter particularly describes the system and method to reduce the effect of the inrush current due to the presence of capacitor load (304) in the circuit. A controller controls the duty cycle using a pulse width modulation (PWM) signal (310) to limit the peak current and preventing the contactor damage which can be caused due to the sudden inrush current. 本主题公开了一种车辆中的预充电系统。本主题具体地描述了用于减少由于电路中电容器负载(304)的存在而引起的浪涌电流的影响的系统和方法。控制器使用脉宽调制(PWM)信号(310)来控制占空比以限制峰值电流，并且防止由于突然的浪涌电流而可能导致的接触器损坏。
