Analysis of the resonance phenomenon in unmatched power cables with the resonance surface response

Power converters are an essential part of modern power systems, giving flexibility to the transportation and allowing insertion a wide range different energy sources. One drawback is that supraharmonic conducted emissions introduced by them can compromise stability these systems through electromagnetic interference (EMI). Electromagnetic compatibility (EMC) filters used prevent such problems. Nevertheless, designed respect standards based on measurements in conditions considerably from real applications. Particularly, if converter connected electrically long cables its may be amplified resonance phenomenon. The method described this paper allows definition for input impedances where cable will not beyond established levels. In some cases visualization three-dimensional surfaces indicating magnitude, frequency position general case defined higher dimensions analyzed with deterministic optimization algorithms. originality resides generalized analysis phenomenon, it frequency-dependent parameters applies unbalanced systems.
