Abstract
Official abstract text for this publication.
An electronic ballast for lighting applications is disclosed. The electronic ballast comprises a first charge pump having an input capacitor ( 13 ) charged with a supply current drawn from a power source by application of a charging voltage to the input capacitor ( 13 ), the magnitude of the supply current being proportional to the magnitude of the charging voltage; and a voltage booster ( 16, 17 ) for generating a boost voltage, which is used to augment the charging voltage, thereby increasing the current drawn from the power source.
