Abstract
Experiments on energy transfer between two superconducting magnets have been carried out using an inductive energy transfer system similar to the flying capacitor system developed at the Karlsruhe Institute. In our system capacitor was grounded and diodes were used instead of thyristors, and a fraction of stored energy was transfered to the capacitor only when the relay connected parallel to the magnet was switched off. The capacitor is expected to have no constraint in size, while in the flying capacitor system the capacitor must exceed a threshold size. Consequently it is possible to shorten transfer time somewhat compared to the one in the flying capacitor system.
Transfer experiments were carried out using a storage magnet with inductance of 1.2H and a load of 0.41H. The capacitance was 200μF. 80.1% of the stored energy of 221J was transfered into the load within about 0.35 seconds.
