Energy storage system pre-charging circuit
A precharge circuit charges the DC-link capacitor to the battery voltage, minimizing the inrush current caused when the main contactors close.
A precharge circuit charges the DC-link capacitor to the battery voltage, minimizing the inrush current caused when the main contactors close.
A pre-charge circuit can be used to prevent stress and damage to the electric system by implementing a resistor and a switch to limit in-rush current.
High-voltage systems (100V+) often use precharged circuits to limit inrush current. This process protects the system from damage, extends lifespan, and increases reliability.
