Precharge board

Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be exposed to high electric current during initial turn-on. This current, if not limited, can cause considerable stress or damage to the system components. In some applicatio… WebJun 11, 2024 · An AC charging Station as the name implies provides AC power form the grid to the EV which is then converted to DC using the On-board charger to charge the vehicle.
