９に並列接続されたフィルムコンデンサである。Embodiment FIG. 1 is a diagram showing a flyback transformer circuit including a capacitor circuit according to an embodiment of the present invention, and the same reference numerals as those in FIG. 2 indicate the same parts. In the figure, 11 is a film capacitor connected in parallel with the electrolytic capacitor 9.
以上の様に、本実施例ではフィルムコンデンサ11を電

フィルムコンデンサ11の容量は電解コンデンサ９の容量
よりも経済的に大きくとれないため出力電圧の安定度は
若干悪くなるが、異常出力電圧となることは防げること
が出来る。As described above, since the film capacitor 11 is connected in parallel to the electrolytic capacitor 9 in this embodiment, even if the capacitance decreases due to dry-up of the electrolytic capacitor or tan δ increases, they are connected in parallel. The film capacitor 11 can maintain the smoothing function. still,
Since the capacity of the film capacitor 11 cannot be economically larger than that of the electrolytic capacitor 9, the stability of the output voltage is slightly deteriorated, but the abnormal output voltage can be prevented.

をはるかにこえるという効果が得られる。Effect of the Invention If the smoothing circuit is only an electrolytic capacitor, the life span is 5 to 10 years, depending on the usage environment, but almost all products with the same design will have a life failure and output voltage abnormality during this period. .. According to the present invention, it is possible to obtain the effect that the life failure is determined by the film capacitor, and the life of the set that becomes the load of the power supply circuit is far exceeded.
