Driving control device and method for thyristor

The invention discloses a driving control device and method for a thyristor. The device comprises: a control unit which transmits a driving control signal; a phase driving unit used for generating a driving signal according to the driving control signal when the circuit where the thyristors are located is electrified so as to drive phase thyristor modules in the circuit where the thyristors are located; and a phase fault detection unit used for detecting the current voltage of the phase thyristor module in a circuit where the thyristor is located after the thyristor is powered on, and outputting a fault feedback signal according to the current voltage. The phase driving unit is also used for regenerating the driving signal according to the driving control signal and the fault feedback signal so as to control the one-phase thyristor module in the circuit where the thyristor is located to be switched off under the condition that the fault feedback signal indicates that the one-phase thyristor module in the circ
