摘      要：Superconducting flux pumps(FP)are capable of supplying superconducting circuits with high currents by additively supplying current over a number of cycles without introducing large amounts of heat into the cryogenic *** FPs can be broadly classified into two types:dynamo and transformer *** the behaviour of these systems is an emerging *** this work a model of a half wave magnetically switched transformer rectifier FP created in MATLAB/Simulink/Simscape is *** existing models,the characteristics of all circuit elements are fully integrated allowing all superconducting elements to be accurately *** presented method uses pre‐calculated look‐up tables,populated with experimentally derived material qualities to simulate these superconducting *** thermal evolution of the switches,calculated simultaneously to the magnetic field switching interaction has also been *** model is compared to the performance of a real world FP during the pumping of a load coil and is found to be ***,the presented model illustrates how small amounts of heating at a magnetic switch can profoundly affect a FPs performance over many cycles.
