Background
The filter capacitor is an energy storage device, is usually installed at two ends of a rectifying circuit to reduce the ripple coefficient of alternating current ripple so as to improve high-efficiency smooth direct current output, and is formed by sandwiching an insulating dielectric medium between two metal electrodes. When a voltage is applied between the two metal electrodes, charge is stored on the electrodes. In the field of strong electricity, alternating current is generally adopted, and the alternating current is often required to be subjected to phase adjustment, so that the power factor, the phase shifting operation and the like of a circuit are ensured. Capacitors are one of the most commonly used devices in circuits that generate heat during operation, which can easily build up to high temperatures if not exhausted in time. The generation of high temperatures will greatly reduce the performance, reliability and life of the capacitor, even if an explosion causes a fire.
