Tatsuya Okada

Title: Tatsuya Okada’s Power-Supply and Overcurrent-Protection Patents.

Introduction

Tatsuya Okada is an inventor associated with Kyoto, Japan. His patent work focuses on power-supply control and circuit protection. The supplied information lists 2 patents and identifies Rohm GmbH as his company.

Latest Patents

Okada’s listed patents address overcurrent protection and power control in power-supply devices.

“Overcurrent protection circuit and power supply device” describes a circuit that combines currents from two mirror transistors to produce a sense current. A current restriction unit controls the drive signal so that the sense current does not exceed a predetermined upper limit, helping protect the power-supply device from excessive current.

“Power control device and power supply device” describes a controller that generates a driving signal for an output transistor based on the output voltage or a corresponding feedback voltage. It also generates a current feedback signal to adjust the output-feedback circuit’s phase characteristics and uses a delay circuit to delay changes in that signal when the output current changes.

Career Highlights

The available information connects Okada’s work with Rohm GmbH and highlights his contributions to power electronics. His listed inventions address both current protection and the control behavior of power-supply circuits.

Collaborations

The supplied information names Atsuhiro Watanabe and Toyokazu Katsumi as Okada’s coworkers. It does not specify their roles in the listed patents.

Conclusion

Tatsuya Okada’s listed patents focus on practical power-supply technologies, including limiting overcurrent and managing feedback in power-control devices.
