いったトラブルを発生させてしまう久々をもっていた。(Prior Art) As shown in FIG. 1, the conventional 7-lash fixing device connects a power source 3 to the primary side of a transformer 1 via a main switch 2, and connects a power source 3 to the secondary side of the transformer 1 via a rectifier 4. The configuration was such that a capacitor 5 and a discharge lamp 6 were connected. Therefore, at the moment when the main switch 2 is closed, and when the capacitor 5 is not charged with electric charge after the discharge lamp 6 is discharged, an inrush current flows through the primary and secondary coils of the transformer 1, which causes the power supply to turn off. 3 voltage changes suddenly,
It has been a long time since I've had troubles such as affecting other equipment, making noise from transformer 1, and shortening the lifespan of capacitor 5.
