Abstract

Apparatus for starting and operating a gas discharge tube comprising a glow discharge starter connected to preheatable electrodes of the tube. An auxiliary circuit including a thyristor produces a voltage to ignite the glow discharge starter which then provides a path to heat the tube electrodes and subsequently aids in generating a voltage peak to ignite the discharge tube. The ignition voltage of the glow discharge starter is chosen to be higher than the AC supply voltage but lower than the voltage produced by the auxiliary circuit.
