Design considerations for a power electronic converter for series connection of wind turbines
Paper i proceeding, 2009
When connecting the wind turbines in series the output voltage will not be constant as in a shunt connection. The common quantity for the turbines will be the current and the output voltage will vary depending on the power production. For the DC/DC converter transformer a toroid shape is proposed and an approximate expression for the electric field inside the transformer were derived and compared with FEM calculations.
