The frequency converter adjusts the voltage and frequency of an output power supply by switching on and off an internal insulated gate bipolar transistor IGBT, provides the required power supply voltage according to the actual requirement of the motor, and further achieves the purposes of energy saving and speed regulation. The safety Y capacitor is usually arranged on the input side of the frequency converter driving circuit, and the safety capacitor is used in the situation that no electric shock is caused after the capacitor fails, and personal safety is not endangered.

At present, in a type test or a factory test of a high-voltage power unit, when a main loop is subjected to a withstand voltage test to the ground, because of the existence of a Y capacitor, a leakage current often exceeds a test standard, so that the test fails, and the existence of the Y capacitor is required when the high-voltage power unit normally works. Therefore, the method often adopted in the type test or the factory test is to remove the Y capacitor or pad the insulating material at the ground point of the Y capacitor, and since the Y capacitor on the driving board is often arranged inside the high-voltage power unit, the high-voltage power unit also needs to be detached when the insulating material is to be pad.
