Can SCR be replaced by TRIAC?
Yes since the SCRs act as the real thyristors
Operation of commutating capacitor?
Commutation Capacitors are usually switched in parallel to the thyristors.
What is reverse breakover voltage in scr?
That depends, you should look it up in the datasheet. For some thyristors it's as low as 6V
Why germanium is not used in fabrication of thyristor?
Germanium is not commonly used in the fabrication of thyristors primarily due to its lower thermal stability and higher leakage current compared to silicon. Silicon's superior electrical properties, including a wider bandgap and better temperature handling, make it more suitable for high-power applications. Additionally, silicon's well-established manufacturing processes and availability further enhance its preference over germanium in thyristor production. As a result, silicon-based thyristors are more reliable and efficient for modern electronic applications.
Why a UJT is not a thyristor?
Because to remain in conduction it requires a supply of emitter current. Without a minimum value of emitter current it can't stay in the on position. Most thyristors do not require gate current after they are turned on to remain in conduction
Why thyristors are preferrred over transistors?
Thyristors are preferred in applications that require the characteristics on a thyristor. Thyristors are quite different to transistors, when they turn on, they stay turned on untill the power source is removed. Transistors conduct as controlled by the emitter current.

What are the switching elements used in high voltage?
There are devices called thyristors which are used for switching purposes in high voltage levels. Thyristors are of different typesSCRIGBDiacTriac, etc.Apart from these MOSFETs, a type of transistor, are also used in high voltage switching applications.
How many number of thyristors are used in the single phase full wave bridge?
A full wave bridge uses 4 diodes to operate. A half wave bridge used 2 diodes to operate. Thyristors used in a full wave bridge are triggered diodes. To make these types of bridges operate a trigger board is required to be connected to the gate input of the thyristor. Thyristors are also known as silicon controlled rectifiers (SCR).
How thyristor control the motor speed?
Thyristors control motor speed by regulating the voltage applied to the motor, which in turn affects its speed. By using phase control techniques, thyristors can adjust the point in the AC cycle at which they are triggered, effectively reducing the average voltage supplied to the motor. This results in a decrease in power and speed. Additionally, thyristors can be employed in various configurations, such as inverters or chopper circuits, further enabling precise speed control in different types of motors.
