Fotovoltaik Sistemler için Yükseltici Tip DA-DA Dönüştürücünün Benzetimi

Günümüzde yenilenebilir enerji kaynaklarının kullanımı giderek artmaktadır. Fotovoltaik sistemler de yenilenebilir enerji kaynakları arasında bulunmaktadır. Bu sistemler bir doğru akım kaynağı olup güneş ışığının olmadığı zamanlarda enerji üretememektedir. Bu çalışmada literatürde yer alan Sert Anahtarlamalı DA-DA yükseltici konvertör ile Yumuşak Anahtarlamalı DA-DA yükseltici konvertörün fotovoltaik sistem üzerinde PID kontrolörle performans analizi yapılmıştır. Matlab/Simulink yazılımında benzetimi gerçekleştirilen konvertörlerin 12-13 V giriş gerilimine karşılık 18 ve 24 V çıkış gerilimindeki performansları izlenmiştir. Çalışmadan elde edilen sonuçlara göre PID kontrolörlü fotovoltaik bir sistem için en başarılı sonuçları Sert Anahtarlamalı DA-DA yükseltici konvertör üretmiştir.

Simulation of Boost Type DC-DC Converter for Photovoltaic Systems

Today, the use of renewable energy sources is increasing. Photovoltaic systems are also among the renewable energy sources. These systems are a direct current source and cannot produce energy when there is no sunlight. In this study, performance analysis of the Hard Switching (HS) DC-DC boost converter and Soft Switching (SS) DC-DC boost converter in the literature with PID controller were performed on the photovoltaic system. The performance of the converters, which were simulated in Matlab/Simulink software was 18 and 24 V output voltage for 12-13 V input voltage. According to the results obtained from the study, the most successful results for a photovoltaic system with PID controller produced Hard Switching DC-DC boost converter.
