Primary VSC is particularly suitable for large load currents (I
smaller voltages. One transformer is used for each load. The following illustrations
show the two stage and three stage VSC connections. Details can be found in the
Thyro-PX VSC connection diagrams,
CAUTION:
In the primary VSC configuration, the mains voltage is stepped up on the
inactive power controller outputs, marked * in the following figure. The
transformer must be designed so that this voltage does not exceed the type
voltage (500 V or 690 V) of the unit, or the unit will be damaged.
ATTENTION:
Dans la configuration principale de VSC, la tension de l'alimentation secteur
est élevée sur les sorties du contrôleur de puissance inactive, indiqué par *
dans l'illustration suivante. Le transformateur doit être conçu de façon à ce
que la tension n'excède par la tension type de l'appareil (500 V ou 690 V);
autrement l'appareil pourrait être endommagé.

Secondary VSC is particularly suitable if many heaters are being supplied from one
transformer. Through the improvement of the power factor, a larger transformer can
dispense more active power and supply additional loads (if required).
