On fully superconducting rectifiers and fluxpumps. A review

In this second part of a review of superconducting rectifiers and fluxpumps, full and half wave superconducting transformer rectifiers are analysed. Modes of operation and loss mechanisms are detailed and a comparison between the behaviour of dynamos and rectifiers is presented. Investigations carried out to date still leave the flux pump relatively a long way from real applications. The possible use of a flux pump in a large magnet system and for the general protection of that system merits further study. (author)
