Stroboscopic instrument having a gate-controlled-switching element and a step-up power means therefor |
摘要 |
A stroboscopic instrument is constructed of a gate-controlled switching element forming a discharge loop that is connected in series with a discharge lamp and main capacitor for storing charge that causes the discharge lamp to flash. The stroboscopic instrument further comprises: a stroboscopic flashing control circuit for controlling the operation of stroboscopic flashing; a low-voltage power supply that has an output voltage lower than the driving voltages of the stroboscopic flashing control circuit and the gate-controlled switching element; a first constant voltage regulator for stepping up the voltage of the low-voltage power supply up to the driving voltage of the stroboscopic flashing control circuit; and a second constant voltage regulator for stepping up the voltage of the low-voltage power supply or the output voltage of the first constant voltage regulator up to the driving voltage of the gate-controlled switching element.
