322038000 | DRIVING MEANS CONTROL | 7 |
20090134848 | ELECTRONIC CONTROL FOR A HYDRAULICALLY DRIVEN GENERATOR - Hydraulic system for driving an auxiliary power source is provided, which is specifically adapted for use with a system for controlling hydraulically driven AC generator. The system includes a hydraulic pump and hydraulic motor that are connected by a fluid circuit. The hydraulic motor drivably connected to an AC generator and is operated in a manner to generate a stable AC power output. The system may include a valve which bypasses fluid around the motor or a variable displacement pump so that the fluid flow rate through the hydraulic motor is controlled in a manner to maintain the desired AC generator output level. Sensors are further provided measuring operating parameters of the system so that the controller can maintain desired operating condition limits | 05-28-2009 |
20130335040 | DRIVE CONTROLLING APPARATUS AND POWER GENERATION CONTROLLING METHOD - In a power generation controlling method, if a first peak of the inverse of the rotation number measured in a first cycle following a plurality of successive cycles is not equal to or lower than a second threshold, it is judged whether or not the first peak is equal to or higher than a third threshold, which is higher than the first threshold. Furthermore, if a second peak of the inverse of the rotation number measured in a second cycle following the first cycle is equal to or lower than a fourth threshold, a target voltage of power generation by a generator a rotating shaft of which is connected to a crank shaft of the four-stroke engine is changed from a normal state voltage to an in-acceleration voltage, which is lower than the normal state voltage. | 12-19-2013 |
20140210425 | POWER GENERATOR DEVICE - A power generator device includes a heavy gyro body, at least one rotation-driving device and a control unit. The heavy gyro body is coupled to a power source and an induction power generator, the power source drives the heavy gyro body to rotate so as to drive the induction power generator to produce electricity. The rotation-driving device is located at an edge of the heavy gyro body and conducting a contact or non-contact interaction with an annular part in reaction to drive the heavy gyro body to rotate about a vertical spindle. The control unit is configured for starting the rotation-driving device to accelerate the speed of the heavy gyro body when a rotation speed of the heavy gyro body is less than a first predetermined rotation speed. | 07-31-2014 |

20090251113 | CORDLESS POWER TRANSFER - A system for cordless transfer of power for appliances or electronic devices | 10-08-2009 |
20120074912 | INVERTER GENERATOR - A control circuit (microcomputer) is provided in each of two inverter portions. Magnitude of a target waveform signal corresponding to a voltage to be output by each of the inverter portions is varied according to an operation state. The number of revolution of the engine is adjusted according to the larger one of the effective powers output from the two inverter portions. To cope with a temporary output shortage from the AC generator, the output voltage is temporarily lowered and then the output voltage is restored after waiting for the number of revolution of the engine increases. | 03-29-2012 |
20120235648 | GENERATOR ROTOR AND BLEED RESISTOR ASSEMBLY - A generator includes a rotor structure has a rotor frame that supports a rotor circuit. The rotor frame is electrically connected to the rotor circuit via a resistive element. | 09-20-2012 |
20140049229 | POWER GENERATION UNIT DRIVER, POWER GENERATION UNIT AND ENERGY OUTPUT EQUIPMENT IN POWER GRID - A power generation unit driver, a power generation unit and energy output equipment in a power grid are described. The power generation unit driver includes a drive controller for generating a drive signal according to a first control signal and a second control signal obtained thereby, a converter for transforming the input energy from a first voltage into a second voltage according to the drive signal and outputting the same to an electric motor connected to the power generation unit driver. The first control signal runs condition information of the electric motor, and the second control signal includes the power grid frequency and/or the voltage amplitude of the power grid. The concept produces improved effects on the stability of power supply by a power grid. | 02-20-2014 |
