ABSTRACT:
A fluorescent lamp stabilizer circuit device of the type comprising two transistor switches is provided. The two transistor switches are alternatively switched on/off so as to control two charging circuits for providing an impulse voltage double that of power supply voltage for initiating operation of a fluorescent lamp to give off light. A resonance circuit is provided to generate a damped oscillation responsive to the impulse voltage to drop output voltage to the fluorescent lamp tube to a rated range immediately after the fluorescent lamp tube has turned on.
