Webto as thyristors. These are all four-layer bipolar devices with various triggering configurations. Regardless of the specific flavor of thyristor used, they all are built on the basic thyristor structure illustrated below in Fig. 4. Fig. 4 - Thyristor Construction Fig. 5 - IV Curve Fig. 5 is the IV curve most commonly associated with WebOptothyristors. PDF Version. Like bipolar transistors, SCRs and TRIACs are also manufactured as light-sensitive devices, the action of impinging light replacing the … WebOpto-isolators are used for driving the 8 Thyristor/SCR’s [11]. The four SCR’s are used in full bridge in anti-parallel connection with the set of four SCR’s as shown in Fig4. Triggering pulse is generated by the microcontroller which fed as the input to the Opto – isolators to drive the respective Thyristor/SCR’s [7]. how to stop verbal abuse from husband
