Abstract

Bu makalede, geliştirilmiş kontrole sahip, yüksek kazançlı, iki aşamalı bir yükseltici dönüştürücü önerilmiştir. Regülasyon kalitesini ve güç yoğunluğunu artırmak amacıyla ortak kontrol stratejisi tanıtılmıştır. Önerilen kontrol yönteminde her yükseltici katı aynı kontrolcü tarafından kontrol edilir. Bu sayede kolay kontrol ve düşük maliyet sağlanır. Ayrıca ara yükseltici katı çıkış gerilimlerinde kontrole bağlı oluşan gerilim yükselmeleri önlenir ve daha düşük gerilimli kondansatör kullanımına olanak sağlanır. Dönüştürücü devresi, 12 VDC giriş geriliminden 42 VDC ve 150 VDC’a çıkacak şekilde iki aşamalı olarak tasarlanmıştır. Önerilen dönüştürücüye ait detaylı teorik analizler yapılmış ve 100 W çıkış gücüne sahip prototip ile doğrulanmıştır. Uygulama devresi üzerinden alınan sonuçlar kullanılarak, önerilen geliştirilmiş kontrole sahip yükseltici dönüştürücü ile geleneksel iki aşamalı yükseltici dönüştürücü karşılaştırılmıştır.

DESIGN AND ANALYSIS OF TWO STAGE BOOST CONVERTER WITH IMPROVED CONTROL

Abstract

In this article, a high-gain two-stage boost converter with improved control is proposed. In order the increase the regulation quality and power density a common control strategy introduced. In the proposed control method, each boost stage is controlled by the same controller. This method provides easy control and low cost and allows the use of lower voltage capacitors at the output of first boost stage. The converter is designed in two stages to increase from 12 VDC input voltage to 42 VDC and 150 VDC. Detailed theoretical analysis of the proposed converter is carried out and validated with a prototype having 100 W output power. Using the results obtained from the application circuit, the proposed boost converter with improved control is compared with the conventional two-stage boost converter operated under the same conditions.
