摘要: This paper investigates the characterization of three-phase EMI filter using S-parameters and use sequence model to fully describe high frequency behavior. Characterization helps understand influence real on overall performance provides information for selection or design. The is divided into two types: component level system level, which can be chosen according design conditions. are as network parameters characterize because convenience measure them in range. Beside circuitry filter, proposed better attenuation conversion between different forms noise, improves understanding towards behavior compared traditional separation common differential mode noise. Corresponding equations provided obtain model. At end, predictions insertion loss energy transfer ratio represent grade based shown with results from conventional measurement method.
