Abstract	This paper considers the Flyback DC/DC converter modeling and controller design for the LED-battery system using PV(Photovoltaic) energy. Recently, they have many concerns about battery charger and DC distribution system for green energy. This paper discusses the modeling of the Flyback DC/DC converter for LED lighting and battery charger with small-signal modeling. Also, the voltage mode control method and the current mode control method are compared for the Flyback DC/DC converter. Frequency-responses predicted by the small-signal modeling is verified by MATLAB simulation. The feature and design considerations are illustrated and verified through the experiment with a 40㎑ MOSFET based experimental circuit.
