Electronic ballasts for gas discharge lamps, including: a zero voltage output sine wave power tube work conduction and conduction angle less than 120 ° collector amplitude modulation single tube or double tube power conversion stage; a basis lightsthe branch impedance angle change control of the boost-starting circuit; Lamp zero voltage across timing heating filament circuit. Without electrolytic capacitor without magnetic ring pulse transformers of the present invention, without the protection circuit, and no power factor correction circuit, without the IC control. To respond flexibly to a variety of lamps and mains voltage, large area using boot inrush current, high power factor, low harmonic. Simple circuit components has the advantage of low-cost, long life.
