Describe the various methods of thyristor turn on?

Answer Posted / Virendra Prakash

Thyristors can be turned on through various methods: Forward Voltage Turn-On, Gate Turn-On (GTO), Light-Activated Switching (LAS), and Reverse Recovery Turn-On. Forward Voltage Turn-On is the most common method where a thyristor starts conducting when its anode voltage exceeds cathode voltage. GTO uses a gate current to initiate conduction, LAS relies on light to trigger switching, and reverse recovery turn-on occurs during the reverse recovery of diodes in a bridge rectifier.

One thing you should remember while trying to solve a math series is that math skills are generally not that important, but rather a vulture’s eye is required to get a strong hold on the unusual, yet a craziest of the logical minds is. Keep this in mind and try to complete the sequence with the appropriate number: 201315, 71280, 9253, 212, ?
