Choice technique develovement of transformer core

변압기 코아의 선정 기술 개발

In this paper, investigated the core of transformer of high power factor and high effectiveness about design and choice technology. Transformer that use existent general core and material is high no-load loss power. Presented core choice method that can reduce loss. Could do to reduce loss according to choice technology of use material more than about 10 (%). Presented classification and check list by Core's type.
