The offered Power Electronics Capacitors are device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. They are capacitors designed especially for use with non-sinusoidal voltages and pulse currents. The Power Electronics Capacitors are very useful.
