Abstract :
A method is presented for predicting time domain steady state ripple voltages in aircraft and aerospace power systems. The method utilizes conducted emissions limits and test data from the equipment and subsystems on the power bus, and a frequency domain bus impedance characterization of the power source. The method is also extended to predict an integrated EMI safety margin (EMISM) relative to a given conducted susceptibility voltage. Calculated results are compared to measurements on an integrated system
