Power converter topologies with energy recovery and grid power limitation for inductive load applications

This work investigates a grid interface for power supplies used in particle accelerators for cycling loads such as large electromagnets. Two topologies are discussed integrating magnetic energy recovery. For each topology, the associated energy management strategies are examined with the objective to control the grid current profile. A model is established for each of the proposed solutions and the simulation results are presented. A critical review of the investigated energy management solutions is attempted.
