Commonly used terms in the Electrical industry.

thyristor rectifier
a rectifier where the switches are thyristors. Thyristors are turned on by a gate trigger signal, and turned off by natural commutation. The output voltage is controllable by adjusting the firing angle of the trigger signal. The direction of the power flow is reversible when an inductive load is used. When the average power flow is from DC to AC, the rectifier is said to be operating in the line-commutated inverter mode.
