Abstract
An HPS starting aid for providing pulses to an HPS lamp via a ballast tap connection, the aid employing a capacitive voltage divider connected to the power distribution line for charging purposes. There is no power resistor so that the pulse width and amplitude is not dependent on voltage amplitude fluctuations of the line voltage. A voltage breakdown device and a timing RC network determine the pulse positioning of the starting pulse. The size of the capacitors in the capacitive voltage divider and the number of turns on the ballast tap winding determine the pulse width and amplitude.
