Abstract

A circuit model for the prediction of conducted emissions due to DC/DC converters in a satellite power-distribution system is proposed. The noise source is represented as a linear network whose parameters are identified from measurements performed in suitable test setups. In particular: (a) the passive part of the model is represented by an admittance matrix; (b) the active part of the model is represented by ideal current sources. The cable (shielded twisted-wire pair) used to connect the DC/DC converter to the power distribution unit is characterized as a transmission line. Experimental validations confirm the effectiveness of the proposed approach.
