Abstract

PURPOSE: To compact a stabilizer by continuously charging a capacitor (which is charged by an AC source) for predetermined period after the making of the AC source, adding the charged voltage of the AC source voltage, and feeding the total voltage to a discharge lamp for starting it.
CONSTITUTION: A transistor Q is fed with base current from a control unit 6 for a predetermined period after the making of an AC source 2, so that there is formed a series circuit consisting of an inductance element 3, capacitor 4, diode bridge B, and the transistor Q and that the capacitor 4 is charged. With the transistor Q turned off by the control unit 6 after the prede ermined period, the charged voltage of the capacitor 4 is added to the voltage of the AC source 2, and the total voltage is fed to a discharge lamp 1 for starting it.
