Improvements in control of current supply to a transformer-rectifier flux pump

Abstract

The technology relates to the field of superconductor transformer-rectifier flux pumps and controlling a supply of alternating current to a transformer-rectifier flux pump to charge a load. A response of the transformer-rectifier flux pump to a characterisation current supply is determined, which may comprise determining values in the flux pump corresponding to values of the applied current. For each of a plurality of target values of load current to be supplied to the load, values of the current supply are calculated. The supply of current to the flux pump is controlled accordingly. The supply may be modified based on feedback received from the flux pump, for example sensors measuring values on the secondary side of the transformer.
