Using the Matrix Pencil in order to analyze the disturbances induced by the radiation of static converters

• We propose the use of Matrix Pencil method for analyzing disturbances emitted by power converters.
• We analyzing the position of the poles and residues and to extract the dominant poles.
• The modeling of the power converter in time domain is realized by solving Maxwell’s equations.
• We use Ampere’s theorem for computing the induced current in passive loops representing the victim.

The Matrix Pencil method is used for extracting maximum information from the Electro-Magnetic disturbances emitted by power converters; these disturbances are manifested by an induced current in electric systems located in the power converter environs. The modeling of the power converter in time domain is realized by solving Maxwell’s equations which allow determining the radiated electromagnetic field, Ampere’s theorem is then used for computing the induced current in passive loops representing the victim system. In our work we also analyze the effect of the geometric configuration for both the passive loops and the power converter by extracting the poles and residues using Matrix Pencil method.
