Miniaturized capacitor for high voltage filter circuit of electric vehicle

Along with this trend, we have seen more electronics in high-intensity lighting, safety systems, transmission and control, and power systems for better drive results. The use of electrical loads to replace traditional mechanical and hydraulic loads in the transmission system has increased the efficiency of the work, which has led the industry to pay more attention to the concept of electric vehicles - hybrid electric vehicles (HEV) and pure electric vehicles (EV).

However, more needs and demands for electric vehicles have brought more challenges to the traditional 12V power system. Similarly, higher withstand voltage is also critical for more efficient and flexible handling of power transmission loads. Switched-mode power supplies (SMPS) provide the basis for this shifting need. In addition, advances in power electronics have also placed demands on the application of higher-grade components such as capacitors with higher withstand voltages, higher capacitances, and smaller capacitors.
