The measurement of the scattering parameter matrix [S] of
the HV battery tested is converted into impedance parameters
[Z]. The impedance parameter matrix [Z] of the simplified
circuit in Fig. 7(a) is known as function of the equivalent circuit
impedances [Z] = f (ZG1, ZX , ZG2 ). The inversion of this
equation system leads to the CM and DM impedances depending
on [Z], as displayed in Fig. 7(b). The resulting CMand DM
impedances are plotted in Fig. 8.
