The high-voltage direct current (HVDC) converter valve (thyristor converter valve) is the core equipment for achieving AC-DC conversion in HVDC transmission systems. The working principle of the converter valve involves controlling the activation of high-power electronic devices (thyristors) to facilitate the conversion between AC and DC power. It is primarily used for long-distance, high-power HVDC transmission and inter-regional grid interconnection.
