High Voltage Direct Current Electricity – technical ...· PDF fileA typical HVDC system is shown in simplified form in Figure 1. A converter at the sending terminal acts as a rectifier and converts the AC power into DC. A converter at the receiving terminal acts as an inverter and converts the DC power into AC. The connection between the converters may be by overhead line, cable, or both.

Key Technologies Used in Hida-Shinano HVDC Link : Leading ... Hida converter station was the first such AC/DC station in Japan to use an imported air-insulated filter (supplied by ABB). The filter is composed of a capacitor bank in which can-type units are connected in series and parallel, an air-core dry-type reactor, and a dry-type resistor, all of which are self-cooled.
