A method and apparatus for connection of a wind driven turbine generator to an HVDC transmission line is provided that does not require transformation of the wind generated AC voltage to a nominal AC distribution grid frequency. An AC output from the turbine generator is increased in level and converted to HVDC for direct application to a HVDC transmission line. The wind turbine generated AC may be first increased in frequency via a matrix converter and then rectified or may be first rectified and increased in level by a high-voltage DC-DC converter circuit and then applied directly to the HVDC transmission line.
