Based on the principal of ‘zero' voltage turn-on and ‘zero' current turn off for capacitors, these switches are manufactured with thyristors in ‘R' and ‘B' phases. Switching times of 40 mili-seconds is possible with these switches. ...
A thyristor is a four-layer semiconductor device, consisting of alternating P type and N type materials (PNPN). The four layers act as bistable switches. As long as the voltage across the device has not reversed (that is, they are forward biased),...
