His work is primarily associated with Denso Corporation, a leading global automotive components manufacturer.

Latest Patents

One of Yagyu's latest patents is an electric power converter. This device is designed with a master converter and a slave converter connected in parallel to a load. The master converter operates with priority over the slave converter. The slave converter features a voltage sensor that detects the output voltage of the electric power converter. It also includes a control unit that regulates the output of the slave converter based on a target command value. The control unit selects a current command value received from the master converter as the target command value when the variation in output voltage is below a certain threshold. Conversely, it selects a voltage command value to suppress output voltage changes when the variation exceeds the threshold.

Another significant patent by Yagyu involves a current detection circuit. In this circuit, a first circuit connects a first terminal to a second terminal, while a second circuit connects a third terminal to a fourth terminal. The second and fourth terminals are commonly connected. When a first current flows between the first and second terminals, a voltage drop occurs in the first circuit. A current control circuit regulates the first current to ensure that the application voltage between the first and second terminals is substantially the same as that between the third and fourth terminals. This design allows for accurate detection of current flow between the terminals.
