Abstract

This paper deals with determination of equivalent circuit parameters of the Low-Tc Superconducting (LTS) power supply for charging of the LTS magnet, as well as analysis of its characteristics as determined through experiments. The power supply consists of two exciters, a rotor, a stator, and an LTS magnet. In this experiment, a 25.8 mH LTS magnet was used, and rotor revolutions from 30 to 300 rpm were used. The magnetic flux distribution analysis of the system was carried out. Based upon this analysis, maximum 150 A dc excitation current was optimally derived. In order to measure the pumping-current with respect to the magnet flux changes, a hall sensor was installed at the center of the LTS magnet. The experimental observations have been compared with the theoretical predictions. In this experiment, the pumping-current has reached about 372 A.
