Film capacitors

Film capacitors for power electronics are used for a variety of applications, even in the presence of extremely non-sinusoidal voltages and pulsed currents. Both AC and DC capacitors are available. AC capacitors are periodi- cally recharged during operation, DC capacitors are periodically charged and discharged without recharge.
