PROBLEM TO BE SOLVED: To resolve such a problem that a drive time of an electronic apparatus is shortened when a current value during power-on is controlled to increase in such a manner that a pulse width of a pulse voltage, which detects a charge completion voltage, reaches equal to or more than a predetermined value with the objective of increasing the accuracy of a charging voltage.SOLUTION: In a stroboscope charge control circuit and a control method of the stroboscope charge control circuit, magnetic energy accumulated by power conversion means is released when an input voltage value drops to equal to or less than a predetermined value, and a time to restart the accumulation is set as a delay time increased by one step from a set value at storage means. |
