摘要： A motor system provided with one motor and two inverters includes a first inverter control unit which changes a frequency of a first carrier wave (first carrier frequency) used for producing a switching signal fora first inverter according to an operating point of the motor; and a second inverter control unit which changes a frequency of a second carrier wave (second carrier frequency) used for producing a switching signal for a second inverter according to an operating point of the motor. The first carrier frequency has a changing characteristic depending on the first inverter control unit and the second carrier frequency has a changing characteristic depending on the second inverter control unit, and the changing characteristics are different from each other to make the first carrier frequency and the second carrier frequency differ from each other at an identical operating point.

摘要： A wind powered turbine with low voltage ride-through capability. An inverter is connected to the output of a turbine generator. The generator output is conditioned by the inverter resulting in an output voltage and current at a frequency and phase angle appropriate for transmission to a three-phase utility grid. A frequency and phase angle sensor is connected to the utility grid operative during a fault on the grid. A control system is connected to the sensor and to the inverter. The control system output is a current command signal enabling the inverter to put out a current waveform, which is of the same phase and frequency as detected by the sensor. The control system synthesizes current waveform templates for all three-phases based on a sensed voltage on one phase and transmits currents to all three-phases of the electrical system based on the synthesized current waveforms.

摘要： A feedback control switching unit of an inverter control unit selects, based on a magnitude relationship between a predetermined switching determination amount and at least one switching threshold, at least one of feedback control units to thereby execute switching among feedback control modes, such as a current feedback control mode and a torque feedback control mode, of the respective feedback control units for driving of the AC motor. A switching command generating unit generates a switching command for an inverter based on a manipulated variable calculated by the selected feedback control unit. When a torque response request determining unit determines that a required torque responsiveness is high, the feedback control switching unit reduces the number of executions of switching among the feedback control modes.

摘要： The invention described above is a method of producing high voltage alternating current electricity for use in the electrolysis of liquid. The advantages of using high voltage alternating current over just direct current are that there are resonant frequencies for functional groups in any chemical. By using high voltage alternating current instead of just direct current new pathways might be found to produce chemicals. Possibly even the production of synthetic fuels. My invention is a tool for use in this experimentation. The high voltage oscilloscope provides for means of controlling both frequency and voltage at a specific test site.

摘要： A hybrid vehicle has an engine and a generator/motor connected through a planetary gear unit to an output shaft and the output of the engine is distributed between the generator and the output shaft. The vehicle is smoothly started by a driving motor. When vehicle speed V reaches an engine starting speed V*, the speed of generator/motor is changed to cause the engine to rotate, the engine is ignited and driving continues with the output torque produced by the engine supplemented by the driving motor. The hybrid vehicle allows for a smooth start and improved driving comfort even if an engine interruption scheme for halting the engine is employed, for example, halting the vehicle while waiting for a traffic signal to change.
