Introduction
A thyristor unit is semiconductor device which acts as
a switch formed by two thyristors in antiparallel.
To switch on the alternating current the input signal
will be on and the thyristor will switch off at first Zero
Crossing voltage with no input signal.
The benefits of thyristor units compared with
elettromechanical contactors are numerouses: no
moving parts, no maintenance and capacity to switch
very fast. Thyristors are the only solution to control
transformers and special loads that change resistance
with temperature and with age.
