Certain magnet power supplies for particle accelerators demand a high consumption of pulsed power, which generates perturbations in the electrical grids located in urban zones. Power supply systems with integrated local energy storage elements are under consideration as alternatives to mitigate these disturbances. Due to elevated magnitudes in the load current, a parallel association of full-bridge structures is proposed to control the energy flow between the storage units and the load. Different modulation methods and interleaved control techniques are used. In the present work, different strategies are analyzed in a comparative study, with the purpose of defining the most suitable one for the operational characteristics considered for both, the load and the storage elements. Simulations on a future power converter to be used in the High-Luminosity Large Hadron Collider (HL-LHC) at the European Organization for Nuclear Research (CERN) are presented.
