Modelling and Simulation of Integrated Topology of DC/DC converter for LED Driver Circuit

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

A Single-Stage LED Driver Based on Interleaved Buck-boost Circuit and LLC Resonant Converter

A single-stage LED driver based on interleaved buck-boost circuit and LLC resonant converter is proposed. The buck-boost circuit and LLC resonant converter are integrated by sharing switches, which can decrease the system cost and improve system efficiency. The input voltage of the buck-boost circuit is half of the rectified voltage, and two buckboost circuits are formed with the two half-bridg...

A Highly Efficient SEPIC-Flyback Integrated Converter as an LED Driver

Light-emitting diodes (LEDs) have been widely used for various lighting applications. A high power factor single-stage single-switch driver can be used to supply LEDs without using an electrolytic capacitor. By integrating the single-ended primary inductor converter (SEPIC) and flyback converter, LED driver could achieve nearly a unity power factor and low total harmonic distortion (THD). Since...
