Resumen:
Power converters associated to inner triplet magnets of the Large Hadron Collider (LHC) are being updated. In this sense, conversion schemes with parallel association of H-bridge structures and integrated local energy storage systems are considered. Different topological structures, modulation techniques and interleaved operating modes are analyzed. A restrictive specification that these converters must satisfy on the load is the compliance of specific limits for each frequency component of the output common mode voltage; since they define Electromagnetic Compatibility (EMC) issues. The evaluation of the common mode voltage spectrum is not a simple operation, since these systems present multiple sources of input noise. The present work proposes a methodology to calculate a transfer function, from an equivalent single-input system, useful to determine the output common mode voltage spectrum. Simulations for a particular converter are presented.
