bcz scr ( silicon controlled rectifier) it's stop flow of current
Answer:
SCR power electronic device is used in speed control of motors.
Explanation:
Power Motor Company created an SCR speed-regulating motor to meet market demand based on fixing issues with current engines. The bidirectional thyristor used to control the speed of the SCR speed control motor is an AC motor.
The following electrical circuit may use SCRs to regulate a DC motor's speed. The input AC voltage is changed into a pulsing dc voltage using two SCRs. The output of the SCR rectifier circuit, which is regulated by the gate pulses' timing, may be changed to alter the pulsing dc voltage.
Connecting SCRS in parallel allows AC power in a load to be managed.
Thyristors are primarily used in AC control circuits where mains (line) voltages are used for loads of several watts, or commonly kilowatts, such as light dimmers, AC motor speed controllers, radiators, and so forth. The purpose of AC Control is to interrupt the SCR component of the circuit during each AC cycle to restrict the amount of average current flowing through the SCR and, as a result, the amount of average power delivered to the load.
