Method and device for feeding an electrical installation , and its use in lamps

Abstract

Abstract Use is made of a storage capacitor (CS) inserted between installation (10) and network (20) and fed through a limiter (30) of its charging current. This limiter is controlled by a regulator unit (40)/controller (40R-40C) dependent upon a programmer (50). This programmer operates so as to bring about starting even when the charge on the capacitor is zero or practically so, and then to raise the charging current in accordance with a programmed law (52) during a transient period and finally to monitor the charge and hold it close to a threshold independently of fluctuations in the network. Application to high-pressure metal-vapour lamps. <IMAGE>
