  • Approximated sinusoidal waveform inverter
    Patent number: 6816394
    Abstract: A DC-to-AC inverter includes a switch stage having a switch output, a switch controller coupled to the switch stage, and a filter coupled to the switch output. The switch stage includes switch means coupled to the switch output for switching the switch output between a pair of power supply rails. The switch controller is configured to cyclically linearly vary the duty cycle of the output signal at the switch output. The filter is configured to produce a piece-wise linear approximated sinusoidal output waveform from the output signal.
    Type: Grant

  • Pitch governing assembly for windmills
    Patent number: 6761533
    Abstract: A pitch governing mounting assembly for a windmill blade and a windmill incorporating such an assembly. The assembly has a first member coupled to a second member in a manner which causes simultaneous axial and rotational movement of the second member relative to the first member. Input for axial movement of the second member relative to the first member is provided by centrifugal force arising from rotation of the windmill blades secured to the second member about a windmill input shaft. A biasing member is provided acting between the second member and the first member to urge the second member toward its first position relative to the first member as centrifugal input diminishes.
