• Simulink R2016a or newer.
• Plexim PLECS 4.5 or newer.
Modeling of DIN50A
The DIN50A model has two modeling levels:
- (A) Simple
- (B) Detailed
A generic sensor can be approximately modeled by an ideal sensor in series with an optional first-order Low-Pass Filter (LPF). The relationship between sensor’s bandwidth \(f_{BW}\) and the time constant \(\tau\) of the LPF follows \(\tau = \frac{1}{2\pi f_{BW}}\).
A sensor is modeled as a first-order LPF only if its bandwidth lies within the frequency range of a given modeling level. Otherwise, it is modeled as an ideal sensor. The following table summarizes the information on the DIN50A voltage sensor.
| Sensor | Bandwidth [kHz] | (A) Simple | (B) Detailed |
|---|---|---|---|
| DIN50A | 200 | Ideal | Ideal |
