Abstract

Bu çalışmada, endoskopi sistemlerinde kullanılmak üzere rezonanslı SEPIC dönüştürücü tabanlı bir LED sürücü tasarımı sunulmaktadır. Yumuşak anahtarlama ile çalışan rezonanslı SEPIC dönüştürücü, güç tüketimini azaltmak ve verimliliği artırmak için iyi bir alternatiftir. Dönüştürücünün tasarımında güç yoğunluğunu artırmak için çalışma frekansı 8 MHz olarak seçilmiştir. Dönüştürücünün tasarımı, tasarım prosedürünü basitleştirmek için literatürde önerilen gerilim tahrikli doğrultucu temel alınarak yapılmıştır. Son olarak, dönüştürücünün performansı, LED yüklü yüksek güç yoğunluğuna sahip bir prototip üzerinde doğrulanmıştır. Dönüştürücünün maksimum verimi %84,5 civarında ölçülürken çıkış gerilimi 2,82 V ve çıkış akımı 1,02 A civarındadır.

Abstract

In this work, a light emitting diode (LED) driver design based on resonant SEPIC converter is presented for using in Endoscopy Systems. The resonant SEPIC converter operating with soft switching is good candidate to reduce the power consumption and increase the efficiency. In the design of the converter, the operation frequency is selected as 8 MHz in order to increase power density as well. The design of the converter is built based on voltage driven rectifier proposed in the literature to simplify the design procedure. Finally, the performance of the converter is verified on a prototype loaded with a LED, which has high power density. The maximum efficiency of the converter is measured around 84.5% while the output voltage is 2.82 V and the output current is around 1.02 A.
