Document Type and Number:
Japanese Patent JP2003513601
Kind Code:
A
Abstract:
An electronic ballast circuit for driving a gas discharge lamp from a mains voltage signal supply includes a ballast bridge unit having upper and lower signal lines. A capacitive divider is disposed across the bridge. The capacitive divider comprises at least two capacitors coupled in series at a common reference voltage signal terminal. The bridge unit also includes two diodes coupled in series at a rectifier common terminal, wherein each of the diodes is respectively coupled to one of the signal lines of the bridge unit. The bridge unit further includes an input converter bridge and an output converter bridge each having at least two switches coupled in series at input and output common terminals, respectively.
