  • High energy density capacitor is a key device in power supply source in Electromagnetic Gun (EMG) system. In order to increase the reliability of the power source equipment, the lifetime of capacitors must be lengthened. The increasing of the capacitor's lifetime is mainly beneficial from its self-healing capability. Nevertheless the self-healing is the main reason for the capacitance loss of metallized film capacitors, and it might finally lead to the failure of a capacitor.
