Description

technical field [0001] The invention relates to the technical field of thyristor triggering, in particular to a high-voltage thyristor wireless triggering device. Background technique [0002] At present, the withstand voltage level of a single thyristor can reach 9000V, but for the power system, its withstand voltage level still cannot meet the requirements. In order to meet the high-voltage requirements of the static frequency converter of the core component of the thyristor main circuit, the thyristors are generally used in series in the device. In order to ensure the safe operation of the thyristors in series, there are complex peripheral circuits around them, which constitute the high-level trigger circuit of the thyristor. Due to the high voltage, the research on the transmission of the thyristor trigger signal becomes the key to the reliable operation of the thyristor. [0003] When the high-voltage synchronous static frequency conversion is applied to the high-volta...
