Sensitivity analysis of the Multiple FeedBack filter in non-sinusoidal regime

摘要

A new method for calculation of first order sensitivity and sensitivity groups for Multiple FeedBack (MFB) filter in non-sinusoidal regime is presented. Such a group of linear dependent parameters is defined the relative input values of current and voltage harmonics. The interdependence of the various network sensitivities for a given network needs special consideration. Numerical example for Butterworth low-pass filter is used for the discussion of some aspects related to the sensitivity groups' problems.
