ABSTRACT:
An installation for controlling the electric supply of charge elements, such as high pressure discharge lighting lamps, which are distributed along supply lines to which are applied an alternating supply voltage and periodical control transitions superposed to said alternating supply with a selected phase angle. The installation comprises supply circuits through which said charge elements are connected across supply lines. Said supply circuit includes a pulse transformer having two windings, one of the windings being connected via a capacitor in parallel to a choke coil. The other winding triggers a controlled switching device which supplies the charge elements.
