Electronic Match

In startup, it is important to ensure that the firing angle that each pair of thyristors count is electronically controlled in order to concentrate a variable voltage at the motor terminals during the acceleration process.

Over the years, the advancement of electronics has ensured the creation and projection of diverse components, such as the solid-state starter, consisting essentially of a set of pairs of thyristors, or combinations of thyristors and diodes, with one at each motor power terminal.    CASC25

Thus, it is possible to be able to sustain the starting current at the line near the nominal line and with a subtle variation. In addition to the advantage of voltage or current control during the start of the match, the electronic key also has the convenience of having no moving parts or bows, as in the case of mechanical switches.

At the end of the starting period, normally adjustable on average, between 2 and 30 seconds, the voltage can reach its full value after a subtle acceleration or an ascending scale, as opposed to being exposed to sudden increases or jumps.
