Why add precharge resistors and precharge relays
Because there are a large number of capacitive loads at the input end of the high-voltage equipment controller, directly connecting the high-voltage main circuit may produce a high-voltage electrical shock, which is easy to break down the capacitor and cause leakage risk. Therefore, in order to avoid the high-voltage electric shock when it is turned on, the high-voltage system needs to use a pre-charging circuit to pre-charge the high-voltage equipment.
