Title: Ryota Okuyama: Innovator in Power Conversion Technology
Introduction
Ryota Okuyama is a prominent inventor based in Chuo-ku, Japan. He has made significant contributions to the field of power conversion technology, holding a total of 7 patents. His innovative work focuses on devices that enhance the efficiency and reliability of electrical systems.
Latest Patents
One of Okuyama's latest inventions is a reactive power compensation device. This device includes a power converter and a converter control unit, which compensates for reactive power in an AC power grid by outputting reactive power from the power converter. The converter control unit features an AC voltage detection unit that monitors voltage information of the connected AC power grid. Additionally, an output limit unit determines if the output reactive power needs to be limited based on the detected voltage information. If necessary, it restricts the output reactive power of the power converter.
Another notable patent is a power conversion device equipped with a control signal gate selection circuit. This device comprises a first control unit and a second control unit that generate a first and second control signal, respectively. A gate circuit allows the selected control signal to pass through, while a drive circuit operates the main circuit based on the control signal. In scenarios where the second control signal is selected while the first control signal is active, the gate circuit interrupts the first control signal, allowing the second control signal to pass through when the instantaneous value of an AC current drops below a threshold current.
Career Highlights
Okuyama has worked with notable companies in the industry, including Toshiba Mitsubishi Electric Industrial Systems Corporation and Mitsubishi Electric Corporation. His experience in these organizations has contributed to his expertise in power conversion technologies.
