Abstract
A new electro-mechanical converter concept for renewables needs a special DC / DC converter.
The converter has to transform a voltage of about 8 kV into a lower voltage of about 400 volts
covering a power range of 250 up to 1,000 W. Using this type of converter, semiconductor
switching elements are required, which can handle a voltage of about 8 kV and carrying a direct
current of about 60 mA.
