Abstract
The invention relates to the electrical engineering, namely to the electronic starting and regulating devices for the luminescent lamps and may be used for starting and controlling the operating current of the luminescent lamps. Summary of the invention consists in that the electronic ballast is additionally provided with a transformer, two primary windings of which are connected in series into the resonant LC-circuit, the first winding being connected to the point between the blocking capacitor and the first electrode of the luminescent lamp, the second one to the point between the same electrode and the capacitor of the resonant LC-circuit. The secondary winding of the transformer has one output connected to the common bus and the second output through the first diode, in the conducting sense, to one of the outputs of the parallel RC-circuit, the second output of which is connected to the common bus. The common bus, in its turn, is connected by means of the second and the third diode, connected in series in conducting sense, with the common point of the parallel RC-circuit and of the first diode. At the same time the capacitor of the frequency setting series RC-circuit of the master oscillator has its free output connected to the common point of the second and third diode.Claims: 1Fig.: 1
