Toyotaka Takashima has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7729145
    Abstract: A power converter that converts an AC power outputted from a generator into a DC power and supplies it to a battery (load). The power converter includes a thyristor (switch unit) connected between an output unit of the generator and the battery (load); and a gate control unit (control unit) for generating a triangle wave voltage having a constant peak voltage corresponding to each cycle of the AC power outputted from the generator, generating a differential voltage between the voltage supplied to the load via the switch unit and a predetermined target voltage, and controlling the conductive state of the switch unit based on the triangle wave voltage and the differential voltage.
