5kW급 비접촉 변압기 설계 및 특성 분석
The Characteristics Analysis and Design for 5kW Contactless Transformer
초록
Contactless systems use electromagnetic fields to transport power from railway substation to the traction system. In Korea Railroad Research Institute, KRRI, the RIPS (Railway Inductive Power Supply), has been developed. The RIPS is based on a contactless transformer with a fixed coreless primary and a moving core, compared with E shape and U shape, in the secondary. The primary coil is supply with 20 kHz current which produces a magnetic flux in the secondary core. Further this flux induces a current in the secondary coil.
