HVDC Power Transmission - an overview | ScienceDirect Topics converter is one of the main components in an HVDC system. The converter used in an HVDC station can either be a 6-pulse or 12-pulse converter. The typical circuit arrangement for a six-pulse converter is shown in Figure 17.12. In a six-pulse converter, the thyristor valve is fired every 60°.
