ABSTRACT:
A starting circuit which is connected in parallel with the lamp. No ballast is required for the starting circuit. The starting circuit uses a pulse transformer, the primary of which is connected into an RC network, the secondary of which is connected in series with a capacitor which prevents current flow at the low frequency open circuit voltage. The circuit being in parallel with the lamp enables the use of low power components such as the pulse transformer, since the lamp operating current does not traverse the circuit as would be the case with a series starting circuit or ballast transformer.
