Abstract: A power supply for an arc lamp. It includes a DC to DC converter which has an input, an output, and a circuit for increasing the voltage received at the input and for supplying the increased voltage to its output. A current sensing circuit is provided for controlling the amount of current delivered to the output. The power supply is capable of quickly igniting and re-igniting arc lamps, is relatively inexpensive to manufacture and is relatively light in weight. The power supply can accept either an AC or DC source over a wide voltage range and increases or decreases the input voltage compared to the output voltage.

It includes a DC converter which has an input, an output, and a circuit for increasing the voltage received at the input and for supplying the increased voltage to its output. A current sensing circuit is provided for controlling the amount of current delivered to the output. An output "H" bridge is coupled to the output of the DC converter for generating a squarewave in response thereto. The power supply is capable of quickly igniting and re-igniting arc lamps, is relatively inexpensive to manufacture and is relatively light in weight. The power supply can accept either an AC or DC source over a wide voltage range and increases or decreases the input voltage compared to the output voltage.
