[0002] Electric vehicles have been widely developed and utilized due to their advantages such as high energy utilization, energy saving and environmental protection. At present, the popularity of new energy vehicles in the vehicle market is constantly increasing. When the power battery of new energy vehicles outputs power, it will generate noise that interferes with the work of other components. The function of the capacitor box is to filter the power source and suppress the noise from propagating outward, avoid interfering with the switching characteristics of internal electronic devices and inverters, and protect driving safety. As the power output of electric drives gradually increases, the voltage and current platforms are further increased, and traditional conventional capacitors are difficult to support. It is necessary to introduce the concept of precision devices and PCBA. However, the electromagnetic interference generated by the motor drive system has large energy and wide bandwidth, which seriously affects the electromagnetic compatibility performance of power electronic equipment in automotive devices. X / Y capacitor boxes have a good inhibitory effect on system electromagnetic interference and are widely used in new energy vehicles.
