Abstract
A fluorescent tube driving device including a first voltage converter, a second voltage converter, an oscillating unit, an inverter, an adjusting unit, a switching unit and a voltage stabilizing unit is provided. The first and the second voltage converters convert an alternating-current (AC) voltage to a first direct-current (DC) voltage and a second DC voltage. The oscillating unit is charged by the first DC voltage to generate a charging voltage and a trigger signal. The adjusting unit is charged by the charging voltage to generate a power supply signal. The switching unit transmits the second DC voltage according to the power supply signal. The voltage stabilizing unit stabilizes the voltage from the switching unit. Both of the oscillating unit and the adjusting unit are charged at a delay speed to synchronously transmit the operation voltage and the trigger signal to a controller in the inverter.
