The inverter fault of new energy vehicle is good again. What happened?

The voltage is unstable. According to the information of car home official website, the fault of inverter is due to the unstable internal capacitor voltage, which can not keep the output voltage stable. After the voltage is stabilized, the inverter of the new energy vehicle is fine again. The inverter of the new energy vehicle converts the direct current energy of the battery into the three-phase alternating current required by the motor, which is the core component of the new energy vehicle, and its performance is directly related to the power output performance of the motor and the endurance of the new energy vehicle.
