Grid Connected Inverter

Öz:
This paper presents solar based single phase grid connected inverter system. In such a system, DC-DCconverter is both used to boost low PV panel voltage and ensures that the solar panel operates atmaximum power while Full bridge inverter injects the maximum power from the solar panel to thegrid. The system is reliable because it does not cause control complexity and also it is preferred toobtain a low THD (Total harmonic distortion). But, the main disadvantages of the converters such as aboost or a flyback type are limited voltage gain and low efficiency. In the proposed topology, the DCDC converter with galvanic insulation and high voltage gain characteristics can connect a low-voltagesolar panel to the grid. Simulation results are given for the system which inverts MPPT voltage rangeof 20-30 V DC to grid voltage of 220 V(rms) at power range of 60-300 W with a unity power factor.

Şebeke Bağlantılı Evirici

Öz:
Bu çalışma, tek fazlı şebekeye bağlı güneş paneli uygulamaları için bir evirici topolojisini sunmaktadır. Böyle bir sistemde, Tam köprü eviricisi güneş panelinden elektrik şebekesine maksimum güç verirken, DA-DA dönüştürücüsü hem düşük PV panel gerilimini arttırmak hem de güneş panelinin maksimum güçte çalışmasını sağlamak için kullanılmaktadır. Sistem, denetim karmaşıklığına neden olmadığından güvenilirdir ve düşük bir THB (Toplam harmonik bozulma)’si olduğundan dolayı tercih edilmektedir. Buna karşın, Boost ve Flyback gibi dönüştürücülerin ana olumsuzlukları sınırlı gerilim kazancına ve düşük verime sahip olmasıdır. Önerilen topolojide, galvanik yalıtımlı ve yüksek gerilim kazançlı DA-DA dönüştürücüsü, düşük gerilimli güneş panelini elektrik şebekesine bağlayabilmektedir. Benzetim sonuçları, 60-300 W'lık güç aralığında,20-30V MPPT gerilim aralığını, 220 V (rms) şebeke gerilimine birim güç faktörü ile çeviren sistem için verilmişti
