Abstract

PURPOSE:To prevent the breakdown of a main capacitor by mounting the power supply device so that time up to luminescence from the charge of the main capacitor is shorter than time until charging voltage after starting the charge of the main capacitor reaches the breakdown voltage of the main capacitor. CONSTITUTION:The time T' up to luminescence from the starting of the charge of the main capacitor is set so as to be shorter than the time T until the charging voltage after commencing the charge of the main capacitor reaches the breakdown voltage of the main capacitor. Accordingly, the breakdown of the capacitor can be prevented without mounting a special overvoltage protective device to the main capacitor by optimally setting sequence signals, such as charging signals, luminous signals, etc., line voltage, the time constant of an impedance element for limiting overcurrents, etc.
