Diode#

The Diode block implements a diode model, the current-voltagecharacteristic of which is described bythe following exponential function (1) :

(1)#\[ i=i_{s}e^{\left(\frac{\mathrm{q}\mathrm{u}}{\mathrm{N}\mathrm{k}\mathrm{T}}\right)} \]

where:

\(i\) - diode current, [A];

\(u\) - diode voltage, [V];

\(i_s\) - saturation current, [А]

\(N\) - emission factor;

\(k\) - Boltzmann constant (1.3806503e–23 [J/K]);

\(q\) - elementary electric charge (1.602176e–19 [C]);

\(T\) - the temperature of the diode for which its other parameters are indicated, [K].
