200 Amper, Yüksek Frekans Anahtarlamalı DA Kaynak Makinesinin Tasarımı ve Gerçeklestirilmesi / Design and Implementation of a 200 Ampere High Frequency Switching DC Welding Machine

2012 
Ozet Bu makalede, 5.6 kW (200 A) gucunde bir ark kaynagi makinesi icin yuksek frekans anahtarlamali guc donusturucu devresi ve bu devrenin denetleyicisinin tasarimi ve gerceklestirilmesi anlatilmaktadir. Guc devresinde ikili ileri (dual forward) DA/DA donusturucu topolojisi kullanilmistir. Modulerligi saglamak icin iki adet donusturucu girisleri seri cikislari paralel olacak bicimde baglanmistir. Makalede, tasarim sureci ayrintili olarak anlatilmakta, benzetim sonuclari ve gerceklestirilen prototip devreyle elde edilen deneysel sonuclar verilmektedir. Abstract Design and implementation of a high frequency switched dcdc converter and its controller for an arc welding machine with a power rating of 5.6 kW (200 A) is described in this paper. Dual forward DC-DC converter topology has been used in the power circuit. Two identical converters have been connected in series input, parallel output structure to obtain modularity. Design of the converter is given in detail as well as the simulation results and experimental results obtained with the prototype converter.
