Design of Residual Discharge Protection for High Voltage System
There is a large amount of capacitance due to the presence of a large amount of capacitance in high-voltage components such as motor controllers and electric air conditioners in high-voltage systems. When the high-voltage main circuit is disconnected, there is still a high voltage and electric energy in the high-voltage system due to the existence of the capacitor of the high-voltage component. In order to avoid harm to people and cars, after the high-voltage system is cut off, the high-voltage power of the capacitor should be released through the resistor connected in parallel in the high-voltage system.
