A question about variable speed (frequency) wind generators 1

[edison123]

The set-up for a variable speed (variable frequency) wind generator is

Wind generator - Active rectifier - Inverter - Line Filter - Trafo - Grid.

Question - Since the generator speed is varying, the generator output voltage also varies. How does the inverter then ensure that output voltage is constant, given that an inverter output voltage cannot exceed its input voltage ? Or is my last theory about inverters wrong ?
