Three-Phase Converters
SIRIO 3PH 7 ALFA 3PHSAP
-
The three-phase converter is an electronic equipment able to vary the RMS value of a sinusoidal voltage by controlling no. 6 controlled, antiparallel-connected conducting diode pairs.Since the wave form is symmetrically split both into positive and negative halfwave, the output voltage average value is not affected and equal to zero. This means that three-phase loads can be fed without gene rating inside the mesh a circulating current with average value other than zero.Moreover, the three-phase converting is obtained with only one control circuit thus ensuring balance between the three linked voltages applied to the load.

LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

DC POWER
VARIABLE TRANSFORMER
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.
