WebA 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.
