Voltage indication means for an electronic flashing device

摘要

Voltage indication means for an electronic flashing device in which a low D.C. voltage is converted to a high D.C. voltage by a DC-DC converter circuit and energy stored in a main discharging capacitor is supplied to a flashing discharge tube to fire it, wherein the charged voltage of the main discharge capacitor is indicated by utilizing the fact that the charged voltage of the main capacitor is in equivalent relation with a voltage generated in the DC-DC converter.
