Abstract

The present invention provides a power converter that can be used to interface a generator (4) that provides variable voltage at variable frequency to a power grid or supply network (14). The generator (4) can be driven at variable speed by a source of driving torque that be a wind turbine or other renewable energy source. The power converter includes a machine rectifier (5) such as a diode bridge that is electrically connected to the stator of the generator (4) and rectifies the stator voltage to give a variable dc link voltage. The dc link voltage is filtered to provide a current source to a step-up inverter (7) (such as a pulse width modulated current source inverter) whose output is precisely regulated to provide the required supply network voltage and frequency.
