AbstractUse of LED lamp for lighting becomes common and power converter for LEDs is critical. This paper is about the design of stable power converter for LED lamp. In the construction of the converter, flyback topology is used together with current-controlled current mode control. LED is a current driven device with low dynamic resistance. This introduces instability to output feedback. Current mode control model with more accurate LED equivalent circuit is built on MATLAB Simulink to analysis the control aspect. A solution is figured out by adding additional resistor to output feedback loop. The proposed method is verified by experimental results. ©2009 IEEE.
