In the framework of a Transfer line (TT2) Consolidation Programme, a number of studies on Energy cycling have been commissioned. Part of this work involves the study of different power electronic system topologies for magnet energy recovery. The key objective of the study is to find topologies and control strategies that result in the control of the peak power required from the power network as well as to recover the magnet energy into capacitor banks with controlled voltage fluctuation. In previous reports, the use of a boost front-end converter and two-quadrant (2Q) converter supplying DC link of a four-quadrant magnet supply were analyzed. From this analysis, different features and figures of merit were considered in order to compare the structures, which allowed to define some considerations that a proper topology should have. Consequently, these considerations were used to define some novel topologies. The previous topologies are brie y summarized, as a starting point to develop some novel structures. The different topologies are evaluated considering the figures of merit and aspects related to the implementation.El monto consignado en el informe técnico corresponde a la totalidad del monto del convenio I+D "Study of Power Converter Topologies suitable for Pulsed Operation with Energy Recovery".
