Three-phase rectifier#

This block is a three-phase bridge rectifier scheme contains a rectifier bridge of six vents in which two three-phasegroups are connected in series, Fig. 1 :

Diode block implements a diode model, the СVD of which is described by the following exponential function (1) :

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

where:

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

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

\(i_s\) - Saturation current, [А];

\(N\) - Emission coefficient;

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

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

\(T\) - the diodes temperature for which their other parameters are indicated, [K].
