چکیده
Design and application of led driver with isolated cuk converter for 10W is realized in this paper especially automotive purposes. The advantage topology than conventional Cuk to have electrical isolation supply load providing same polarity output. Besides, power model including constant voltage exponential models obtained employed simulation study comparison. Furthermore, maximum current limitation provided via dsPIC30f4011 microcontroller. Also, switch operated by 100 kHz switching frequency, connection the source LC parallel damping filter, whose noise reduction shown as well. With experimental set up, proving desired results achieved converter, current-voltage, input voltage-current are measured. Simulation also verifies application. Moreover, provides more accurate model.

DC to DC Power for Driving LED-Backlit LCDs
by Michael Keene, Design Engineer Endicott Research Group, Inc. Abstract As LED backlights continue to displace CCFLs in LCDs, display manufacturers have to deal with several important decisions regarding the choice and arrangement of these LEDs and how best to drive them. One major decision is whether to use a large number of low-power LEDs, or a smaller number of mediumto high-power LEDs. The...

متن کاملA CUK Converter Based High Gain Input-Parallel Output-Series Dc/Dc Converter
Due to the decade of fossil fuels at present renewable energy plays an important role in generating power to meet the load requirements. Power produced from the renewable energy is very low. So chopper circuit is required to boost the voltage level of renewable energy sources. Chopper is a circuit in which fixed DC voltage is converted into variable voltage. There are many types of chopper circ...
متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
