The invention relates to the field of power system devices, in particular to a novel method for triggering thyristor for converter valve module test. The triggering method adopts a digital triggering technology, and VBE (Valve-Based Equipment) receives a synchronous signal and can generate a triggering coded pulse with any phase angle which can be conveniently and flexibly adjusted according to the synchronous signal. The reliable triggering of a thyristor under a low voltage is a basis for ensuring the normal and reliable operation of a converter valve and needs two conditions: (1) the voltage difference between the anode and the cathode of the thyristor is a positive voltage, and (2) the thyristor can be triggered and conducted only when the triggering pulse is received. The triggering pulse for reliably triggering the thyristor under a low voltage is provided by TE (Thyristor Electronics), a low-voltage circuit provides the TE with energy for normal work, the TE receives and decodes the triggering coded pulse from the VBE and then provides a voltage and a current to trigger and conduct the thyristor through a power amplifier so as to trigger and conduct the thyristor.
