Study on modeling and operating characteristics of DC transformer
摘要
Abstract
DC current measurement issue is getting more and more attention. This paper focus on the simulation of DC Transformer and the study of model parameters. The sensing mechanism of DC transformer is analyzed and the mathe-matical model for the magnetization curve is built. Then the DC transformer model using the principle of magnetic mod-ulation is created based on the MATAB platform. The DC transformer model contains the physical mechanism of real one, so the transmission characteristics of DC transformers can be studied by changing the model parameters. The simu-lation results verified the DC transformer operational characteristics on low load conditions. The results have compara-ble significance to further study of DC transformer and products design.关键词
