Which description is ture in normal operation characteristics of Thyristor?
选项：

A:Due to the load inductance, thyristor may flow through the reverse anode current;
B:As long as the gate has a trigger current, the thyristor can be turned on;
C:Once the thyristor is turned on, the gate loses its control function;
D:In order to turn off the thyristor conducting, the anode current flowing through the thyristor should be reduced below the holding current
