Low voltage discharge lamp power supply

摘要

A power supply for a gas discharge lamp has an oscillating circuit with two switches connected at a node in series and controlled by an oscillation ignition circuit having a diode that operates above a selected voltage threshold level. An energy storage circuit is connected to the node of the oscillating circuit switches and to the oscillation ignition circuit. It supplies energy to the oscillation ignition circuit and the oscillating circuit while voltage is momentarily below the selected voltage threshold level of the diode.
