Description : Define: i) Firing angle ii) Conduction angle

Last Answer : i) Firing angle: The firing angle of a thyristor is defined as the angle between the zero crossing of the applied voltage and the instant at which the thyristor is triggered or fired. It is a ... off. It is a measure of the duration for which the thyristor conducts current during each AC cycle.

Description : When the firing angle a of a single-phase, fully controlled rectifier feeding constant direct current into a load is 30°, the displacement power factor of the rectifier is

Last Answer : When the firing angle a of a single-phase, fully controlled rectifier feeding constant direct current into a load is 30°, the displacement power factor of the rectifier is √3/2

Description : What is meant by firing angle of thyristor?

Last Answer : The point at which SCR is triggered is known as firings angle of thyristor.

Description : what is firing angle?

Last Answer : Firing angle is time in electrical degrees from the instant the valve voltage is positive to the application of firing pulse to the valve (start of conduction). Also called delay angle.
