This photo shows the out line of a valve module for 500kV thyristor valve. The module contains 7 light-triggered thyristors and their auxiliary circuits. The thyristors, resistors for snubber circuit and coils for valve reactor are cooled by de-ionized water. All the components including valve reactor and mechanism of thyristor stacking were developed to minimize the power loss, size and weight of the module.
