Abstract The invention relates to an electronic ballast with repeatedly resonanting ignition circuit for metal lamps. The converter circuit, control power circuit and repeatedly resonanting ignition circuit are integrated in a bridge converter circuit. By coupling energy of passive storing energy elements to obtain high voltage so as to lighten the lamp, the electronic ballast of the invention does not need an extra ignition circuit. After igniting, the passive storing energy elements can perform as a filter, and corporate with the driving signal of the bridge converter circuit to convert current and control power. Therefore, the electronic ballast of the invention had the higher the energy converting efficiency and reliability, and reduce the volume and the cost.
