High speed operation of the superconducting power electronics device (S-PED) has been observed. Obtained results reveal the possibility of "Thermally-Controlled Superconducting Switch" for rectifying device.(1) S-PED with heat exchenger has been made. It improved 10% heater and cooling efficiency compaired with no heat exchenger.(2)The relationship between the heater inout voltage, the pulse width, the generation speed of the resistance the maximum generated resistance, and the recovery time have been cleared.(3) If the voltage across the S-PED is not large, there is a possibility to develop the rectifire at line frequency.The research and development are reqired to reduce the turn off gate energy. With this fund, the performance test of developed S-PED and the preparation of improvement for the heater efficiency have been performed. It is established the method to yield the improved device.

已经观察到超导电源设备（S-PED）的高速运行。获得的结果揭示了对整流装置的“热控制超导开关”的可能性。（1）使用热交换器进行了S-PED。它提高了10％的加热器和没有热交换器的冷却效率。（2）加热器INOUT电压，脉冲宽度，电阻的产生速度，最大产生的电阻和恢复时间之间的关系。（3）。（3 ）如果S-PED上的电压不大，则有可能在线路频率下开发整流。研究和开发将被重新确定以减少关闭栅极能量。通过该基金，已经进行了开发S-PED的性能测试以及加热器效率的改进准备。它建立了生产改进的设备的方法。
