LED luminaires need a driver circuit for working properly. Most of the drivers have disadvantages such as losses during operation. This issue becomes more important while supplying with limited sources renewables. To overcome problem, this study proposes novel energy efficient based on zero voltage switching (ZVS) single-ended primary inductance converter (SEPIC) technology. Driver and hence we...

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...

LEDs lights have numerous advantages as compared to conventional lighting sources and are becoming popular these days. Depending upon the application requirement brightness of the LEDs needs to be controlled. The brightness is controlled by controlling the forward current flowing through the LED. In this paper, different techniques used for dimming the brightness of LED lamps are reviewed. DC-D...

<span lang="EN-US">As the load demand continues to rise on a daily basis, there will be an increased requirement for sources of renewable energy. When compared building entire power system, cost distributed generation, also known as DG, is significantly lower, which makes it useful tool fulfilling electricity. However, these DG are built utilizing energy, by their very nature intermittent...

Single-ended primary-inductor converter (SEPIC) based differential inverters (SEPIC-BDI) have received wide concerns in renewable energy applications due to their modularity, galvanic isolation, decreased power stages, continuous input current, and step up/down capability. However, its design still has several challenges related component design, the existence of complex right half plane (RHP) ...

In power electronics, it is necessary to select the best converter circuit topology that has good performance among different converters. The single-ended primary inductor (SEPIC) and advantageous direct current/direct current (DC/DC) this paper, a design of SEPIC made by selecting values its components according required output voltage power. an assumption both inductors have same value. teste...

--There are several approaches to nonisolated dc-dc conversion for use when the input varies above and below the output. Among these are the SEPIC, buck-boost and others involving a combination of buck and boost circuits. This paper contains an analysis of four types, with particular attention to the efficiency in a typical application.

This paper presents analysis, modeling, and design of a low-harmonic, isolated, active-clamped SEPIC rectifier for future avionics applications. Simpler converter dynamics, high switching frequency, zerovoltage-switching, and a single-layer transformer construction result in an efficiency of 90% and a very low total harmonic distortion over 400 -800 Hz line frequency variation.
