THIN-FILM CAPACITOR DEVICE

The present invention provides a thin-film capacitor device having a charging circuit and a discharge circuit and capable of stably producing a constant voltage during discharging a thin-film capacitor by an inexpensive configuration. The thin-film capacitor device is characterized by a hybrid type for temporarily storing charge upon receiving DC current from the thin-film capacitor while the voltage becomes lowering, and for supplying DC current in a state of a DC/DC inverter having a base voltage remaining so that a discharge effect continues until the amount of storage in the thin-film capacitor completely runs out.
