Optimized Magnetic Components Improve Efficiency of Compact Fluorescent Lamps

Further improvements in the efficiency of compact fluorescent lamps can be achieved by optimizing the magnetic components in the electronic ballast. Resonant inductors were evaluated in several commercial integrally ballasted lamps. Winding optimization programs were used to redesign the windings of an example inductor. Two of the proposed winding designs were built and confirmed to provide reductions in winding loss of over 40%
