Design solutions for compact high current pulse transformers for particle accelerators' magnets powering

High current pulse transformers are widely used in particle accelerators for feeding pulsed magnets. Usually they need to be installed in very confined spaces, thus requiring compact design solutions. Several magnetic bias solutions are explored with the objective of reducing the core volume and total cost of the converter-transformer system. A concrete example is illustrated via the optimal design of two variants of the same pulse transformer, one with an air-gap and the other without air-gap but with an active magnetic reset. Results show that several solutions exist in order to optimize the volume of pulse transformers; however, this is always done at the expense of a more complex power converter topology or increased magnet volume.
