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.

Crowbar Resistors
-
Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

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.
