Abstract

Bu çalışmada, yüksek gerilim kazancı için hibrit bir DC-DC yükseltici dönüştürücü önerilmiştir. Önerilen dönüştürücü analiz edilmiş ve tasarlanmıştır. Sert anahtarlamadan kaynaklanan kayıpları azaltmak için önerilen dönüştürücüye aktif yumuşak anahtarlama yöntemi uygulanmıştır. Önerilen dönüştürücünün ana anahtarı kesimdeyken, gerilim geçişi sırasında ana anahtar akımı sıfır, tersi durumda ise akım geçişi sırasında ana anahtar gerilimi sıfırdır. Böylece ana anahtarın her iki durumu için de güç kayıpları minimize edilmiştir. Farklı yükler için MOSFET ve IGBT tabanlı aktif yumuşak anahtarlamalı hibrit DC-DC yükseltici dönüştürücü benzetim çalışması yapılmıştır.

Soft Switching for MOSFET and IGBT Based Hybrid DC-DC Boost Converter

Abstract

In this study, a hybrid DC-DC boost converter was proposed for high voltage gain. The proposed converter was analyzed and designed. The active soft switching method was applied to proposed converter to reduce the losses due to hard switching. While the main switch of proposed converter is turning off, the main switch current is zero during voltage transition and in the opposite case, the main switch voltage is zero during current transition. Thus, power losses for both states of the main switch were minimized. The simulation for MOSFET and IGBT based hybrid DC-DC boost converter with active soft switching were obtained for different loads.
