The impedance model represents a series connection of a resistor and either an inductor or capacitor.
The linear impedance connects the complex voltage v
with the
complex current i
by i*Z = v
.
The impedance Z_ref = R_ref + j*X_ref
is given as complex input signal, representing the
resistive and reactive component of the input impedance. The resistive
component is modeled temperature dependent, so the real part R_actual = real(Z)
is determined from
the actual operating temperature and the reference input resistance real(Z_ref)
.
The reactive component X_actual = imag(Z)
is equal to imag(Z_ref)
if frequencyDependent = false
.
Frequency dependency is considered by frequencyDependent = true
, distinguishing two cases:
imag(Z_ref) > 0
: inductive caseX_actual
is proportional to f/f_ref
imag(Z_ref) < 0
: capacitive caseX_actual
is proportional to f_ref/f
A zero crossing of the real or imaginary part of the impedance signal Z_ref
could cause
singularities due to the actual structure of the connected network.
