Draw transistor model of thyristor & explain d analogy? Explain its operating characteristics , limitations etc

Question

Accepted Answer

A thyristor can be represented by a transistor model. It has specific operating characteristics and limitations.

A thyristor can be represented by a transistor model with additional components.
The transistor model of a thyristor consists of two transistors connected in a feedback configuration.
The base-emitter junction of one transistor is connected to the collector of the other transistor.
The analogy is based on the fact that both transistors and thyristors are semiconductor devices.
The operating characteristics of a thyristor include forward blocking, forward conduction, and reverse blocking.
During forward blocking, the thyristor behaves as an open circuit.
When a forward voltage is applied, the thyristor enters forward conduction and allows current to flow.
Reverse blocking occurs when a reverse voltage is applied, preventing current flow.
The limitations of thyristors include high switching times, limited frequency response, and high power dissipation.
Thyristors are commonly used in applications such as power control, motor control, and lighting systems.
