working principle of energy storage pre-charging circuit

In a high voltage system, a typical block diagram may consist of two high current contactors with a separate pre-charge contactor, and a DC link capacitor in parallel with a load (for example, traction inverter).

Without a pre-charge circuit, welding can occur within the contactor as it closes and there could be a brief arc resulting in pitting. Figure 1. Pre-charge Initial State In a high voltage system, a typical block diagram may consist of two high current contactors with a separate pre-charge

cy disconnect when the motor regulator fails. Without a pre-charge circuit, welding can occur within the contactor as it closes and th re could e a brief arc resulting ent of the input capacitances of the circuit. Failure to manage inrush current c n lead to damaged cables,connectors,or fuses.

­An inrush current, also referred to as input surge current, or switch on surge, is the high current, which is often drawn when circuits are initially switched on. Power converters can have inrush currents that are many times higher than their steady-state currents. This is due to the initial
