摘要
该文介绍了一个可用于氧化物超导体临界电流和 I—V 曲线测量的50安培脉冲电源,报告了用该电源对 YB_a_2Cu_3O_(7-x)体材料进行测量的结果。和直流测量结果比较后发现,脉冲测量能有效地消除直流测量中无法避免的热效应。
We describe a pulse power supply of 50 A which can be used in measuring critical currents and I-V characteristics of oxide superconductors. The I-V characteristic measurements for bulk YBa3Cu3O7-x using the supply is reported. In comparison with the DC measurement, We find that the heat effect can be avoided successfully over a great range of current in the pulse measurement.
