  • Patent number: 8766465
    Abstract: Systems and apparatuses for delivering power and energy using deflecting beams or other oscillating members motivated to oscillate a beam assembly using an eccentrically balanced rotating body that induces deflections in the elastic beam or other oscillating member. One or more rotors may be used on the elastic beams and a mechanical output or outputs are connected to the elastic beams. The rotating body is advantageously maintained in rotation by pulses of electro-magnetic force. The oscillating beam or members are preferably driven at a natural resonant frequency to minimize losses and render more efficient the output which can be obtained. The pulse motor or motors can be powered using stored electrical energy, such as may be generated from solar panels, wind generators or other energy storage devices. One or more outputs may be used to drive heat pumps, compressors, pumps or other equipment to assist in independent energy systems.

  • Patent number: 8759995
    Abstract: The control method of a wind turbine generator increases the speed range of wind turbine generators, maximizing the operation and efficiency thereof, in addition to lengthening their service life, on minimizing the extreme and fatigue loads to which the wind turbine generators are subject, and which are due mainly to the stops and disconnections thereof as a result of strong gusts of wind. More specifically, the control method of the present invention stands out essentially for being based on the control of the reactive current circulating through the electric generator, said reactive current control being carried out in accordance with the rotational speed (?g) for the purpose of reducing the voltage at the converter terminals on the generator side, or rotor voltage (VR), which ultimately allows a transitional increase in the speed range of the wind turbine generator.

  • Patent number: 8742614
    Abstract: The invention is a power generator using intermittent fluid flow. The invention facilitates the harnessing of electric power from intermittent wind sources. The apparatus includes panels that are pivotally attached to a frame at a substantially horizontal orientation or are at an acute angle to the horizontal. As wind blows, the panels lift upward relative to the horizontal. Alternatively, the panels may be vertical and attached to an inclined track where the panels move up the track as the wind blows. This motion is transferred to a permanent magnet alternator either via the rotation of a shaft at the pivot point or via a connector rod attached to a leading edge of the panel. The motion may also be transferred by actuating a hydraulic cylinder. This motion pressurizes the cylinder and the pressurized hydraulic fluid may later be transferred into electric power via a hydraulic generator.

  • Patent number: 8710807
    Abstract: A generator has a field coil of a rotor, an armature coil of a stator, a control device supplying an exciting current to the field coil when detecting rotation of the rotor, and a control circuit alternately setting an upper arm transistor and a lower arm transistor in on state in a rectifier module to generate a phase voltage. The control device detects the rotation from a periodic change in a sign of the difference between the phase voltage and a reference voltage. When the rectifier module is overheated, the control circuit sets the upper arm transistor in the off state and sets the lower arm transistor in the on state to almost fix the phase voltage, the control device detects no rotation and stops supplying the exciting current, and the rectifier module generates no phase voltage to decrease temperature of the rectifier module.
