Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

The circuit above is in steady state with the switch open and the SCR is in the conducting state. The voltage drop across the SCR is 1 V while it is conducting. The switch is then closed at t = 0 , ...

A gate turn-off switch, also known as a gate-controlled switch (GCS) or gate turn-off thyristor (GTO), is similar to an SCR but can be turned off by a negative signal on the gate terminal. GTOs ...

The SCR is a switching semiconductor device, whose theoretical basics were published by Moll et al. in 1956 1. Although lower power parts have almost disappeared from the contemporary switching scene ...
