Diode Thyristor Rectifier
Description of Diode Thyristor Rectifier
What is a thyristor?
The thyristor may be considered a rather an unusual form of
electronics component because it consists of four layers of
differently doped silicon rather than the three layers of the
conventional bipolar transistors.
Whereas conventional bipolar transistors may have a p-n-p or n-p-n structure with the electrodes named collector, base and emitter, the thyristor has a p-n-p-n structure with the outer layers with their electrodes referred to as the anode (n-type) and the cathode (p-type). The control terminal of the SCR is named the gate and it is connected to the p-type layer that adjoins the cathode layer.
