Compact single-stage electronic ballast circuit for emergency lighting applications
A compact single-stage electronic ballast circuit for emergency lighting applications, integrating the functions of a flyback charger, a flyback discharger and a half-bridge series resonant parallel loaded electronic ballast into a single-stage electronic ballast. The present invention only employs two active switches so as to achieve an electronic ballast for emergency lighting applications when the electricity is out. Furthermore, the present invention reduces the fabrication cost by simplifying the circuit configuration and reducing the number of employed active switching elements.
