    “…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. …”
