Introduction

Sho Nakagawa is an inventor based in Matsumoto, Japan, associated with Fuji Electric Co., Ltd. His patent work addresses driver-circuit control and the management of current when a switching device operates above a specified threshold.

Latest Patents

Nakagawa is credited with 1 patent: “Driver Circuit with Temperature Detection Circuit.” The invention describes a driver circuit with a switching device, a current-detection circuit, and a control circuit. When the detected drive current exceeds a predetermined value, the control circuit adjusts the switching device’s control-electrode voltage so the current continues to flow at a reduced level. If the over-threshold condition persists for a specified period, the circuit changes the voltage again to reduce the current further. The patent’s description focuses on this staged current-control behavior.
