Abstract:
A wind turbine comprising:a rotor with at least one blade; an permanent magnet alternator with a rotating portion attached to said rotor for rotation therewith and an armature that generates alternating current electricity when said rotating portion turns, wherein said armature has an internal inductance; a rectifier for converting said AC electricity from said armature into a DC voltage; a power circuit operatively coupled to said rectifier for selectively shorting the AC voltage from said armature so as to store electrical energy within said internal inductance of said armature; and an inverter for converting said DC voltage to AC voltage suitable for connection to a utility grid wherein said power circuit boosts said DC voltage to a level sufficient to allow said inverter to operate without a boost function within said inverter.
