Abstract: Light-emitting diodes (LEDs) have become increasingly popular as solid-state lighting sources nowadays. DC-DC conversion has greater importance in LED driver circuit. DC-DC conversion can be reliably performed using LUO converter. It employs voltage lift technique so that output voltage is increased stage by stage. The LED driver could achieve nearly a unit power factor by operating the LUO circuit at discontinuous conduction mode. The voltage lift technique is a popular method that is widely applied in electronic circuit design. This technique gives a good way is improving circuit characteristic and has been successfully applied for DC-DC converter. LUO converters are DC-DC step-up converter using only one switch. The major benefits of this proposed scheme is that it combines the advantages of the switched capacitor, voltage lift technique and the impedance network. MATLAB Simulink has been used to show existing and proposed system results.
