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 Super lift 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 Super lift 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. Super lift 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. |
