Latest Patents

Oshiro is credited with 1 patent: “Insulation Detecting Device for Non-Grounded Power Source.” The invention uses a capacitor and a DC power source insulated from ground. Switching units connect the capacitor to the power source and then to its positive and negative terminals relative to ground for specified intervals. After the switching sequence, a voltage-detecting unit measures the capacitor voltage, and a computing unit estimates the power-source voltage. This approach is designed to detect insulation conditions without requiring the power source to be grounded.
