Thyristor is a four layer system shaped by alternate combination of p and n sort semiconductor supplies. SCR is the principally used member of thyristor household and it is the name generally used when we speak about thyristors. SCR additionally permits the move of current in one course and its motion is managed by an exterior set off pulse applied at its gate terminal.

What Are The Similarities Between A Diode And A Transistor?

The thyristor has three p-n junctions (serially named J1, J2, J3 from the anode). It has a punch-through construction and combines the features of a regenerative thyristor and a MOS-gate construction. The construction is such that the MOSFETs are organized on high of an SCR. The structure can be understood higher with the assistance of the equivalent diagram. A Thyristor is a3N with PNPN junctions, works as a perfect swap & also used for rectification. A Transistor is a2N with NPN or PNP junction, can be utilized as switch or voltage regulator.



Once the switching diode is activated then the forward voltage can be detached. The required time for the switching diode to off from ON is recognized as the reverse recovery time. In basic, this time is greater as compared to the turn-on time. Similarly, once the ‘S1’ switch is closed, then the DC voltage is supplied to the positive terminal of the VD1 diode by way of R1 to modify on VD1.
