A new HVDC transmission system, CSWHFR, has been presented to reduce the cost of energy transmission from offshore wind farms to shore. This system allows the direct connection of wind turbines to a medium voltage DC distribution line. This new converter, which is composed by a six-pulse square IGBT inverter, a high frequency transformer and a thyristor rectifier, presents zero voltage switching at IGBT turn on, allowing to reduce the power loss.
