Abstract
A discharge lamp starter includes a DC/DC converter. The DC/DC converter includes a forward section for producing a first output voltage that is determined by a power supply voltage and a turn ratio of a transformer, and a flyback section for producing a second output voltage that is determined by an inductance of a primary winding of the transformer and a current flowing through the primary winding. The DC/DC converter generates its output voltage by adding the first output voltage and the second output voltage. The configuration can reduce the size of the discharge lamp starter.
