WebFig. 4 illustrates the use of a SCR as a halfwave rectifier. When SW4 is pressed current flows to the gate during the positive half-cycle turning on the SCR. The SCR stays off during the negative half-cycle. The output voltage is RMS * 0.9 / 2 = 10.8 volts. Switch SW3 is not needed. Fig. 5. In Fig. 5 we have a H11C4 used to turn on a light bulb. WebSilicon-Controlled Rectifier. The SCR is a three-terminal thyristor that acts like a silicon rectifier diode whose conductor is controlled by an input current. The schematic symbol for an SCR is shown in Fig. 12.21. The symbol is similar to that of a diode with a cathode and an anode. Note that the third element of the SCR is known as the gate.
