In the experiment equipment , the transformer in question is formed by the Yy0 connection of the transformer with one phase each of which is really 500VA , 220/ 110V 50Hz mantel type. Two loads with various electrical features in order to use in the equipment for obtaining experimental data. In these load types, the interaction of the transformers from the harmonics are simultaneously measured by two harmonics analysers connected to primary and secondary . In Microsoft – Excel programme, equivalent circuit components are separetly calculated for each harmonic component . By means of measured and estimated values , copper losses and iron losses of primary and secondary circuit of the transformer with three phases and efficiencies of the transformer are calculated. All the measurements and calculations for...

Bu alaka gunes enerjisi, gunes paneli yardimiyla elektrik enerjisine donusturulmeye basladiginda ilgi baska yone evrildi. Bugune kadar, fotovoltaik modulden maksimum enerjiyi elde etmek icin farkli tiplerde guc elektronigi yontemleri olmustur. Maksimum guc noktasi izleme (MPPT) algoritmasi, fotovoltaik (PV) kaynagin maksimum guc lokusu ile yuk eslesmesi saglar ve bu yontemde PV gucu, isinlama ve sicaklik gibi farkli cevresel faktorler icin maksimum seviyesinde kalir. Bu calismada ise MPPT algoritmalarindan artimli iletkenlik teknigi ozetlenmis ve bu maksimum guc noktasi izleme yontemi Orta Anadolu yaz mevsiminin ortalama hava kosullari baz alinarak simule edilmistir. Artimli iletkenlik yonteminde, gucun PV gerilimine gore turevi maksimum guc noktasinda sifir, tepenin sag tarafi icin negatif ve tepenin sol tarafi icin pozitiftir. Bu turev sifir ise herhangi bir ...
