*6.2.1. Internal structure of the rectifier block*

The structure of the rectifier block is presented on figure 20a. Four different blocks can be seen on this scheme: the first one called "Control T" is used for the control of the thyristor gate. The second one called MF1 is used to compute the inductances state and voltage. The third called Current computes inductances currents. Then, the Initial Phase block computes the initial state for next computing phase.

The computing algorithm has been created in accordance with figure 20b. For each computing step, the new operating phase is calculated. This phase is a function of the initial phase, the sign of the inductance currents and the diode voltages. For each operating phase, the value of each inductance di/dt is calculated and permits to know the diodes currents with the integrator function.

The current block is strictly identical to the current block shown in figure 16.
