This paper proposes an electronic driver for public lighting systems. The input stage is based on the integration of two flyback converters with different polarities, in order to avoid the use of the input diode bridge rectifying stage. The output stage is a boost converter with an output current control. The proposed circuit is introduced and analyzed, and a design example for a 50-W light-emitting...
This work proposes a new topology based on the integration of two flyback converters with different polarities, in order to avoid the use of the input diode full-bridge rectifying stage. The design is presented and analyzed, and a design example for a 50W LED lamp is presented, along with some simulation and experimental results, in order to validate the idea. A comparison in terms of efficiency is...
