Function "Linearization of gating unit characteristic":
This function is only used for internal Siemens applications (THYRISIEM® excitation equipment).
x: Input variable (CI: p50600[4], í100 % to +100 %).
y: Firing angle linearized (CO: r52128, í100 % to +100 %).
Firing angle that is required so that, with B6 switching and a non-pulsating current,
the output voltage changes linearly with the input variable.
