Latest Patents

Matsumoto’s two listed patents concern vehicle power supplies.

“Power supply device for a vehicle” describes a high-voltage supply made from battery modules connected in series. A safety plug unit connects or disconnects the modules’ electrode terminals, while the corresponding female electrode bodies are arranged at equal intervals within a limited area. Each module’s output is designed to remain below 50 volts, helping reduce the risk of injury during use, inspection, and maintenance while also supporting a more compact device.

“Power supply for a vehicle” presents a system that supplies high-voltage power to a vehicle’s drive motor. Its series-connected battery modules establish an electrical neutral point, and a three-level power supply line provides potentials of +150 volts and −150 volts relative to that point. A three-level inverter converts direct current into three-phase alternating current to drive the motor. The design can reduce the voltage-withstand requirements of connected control units and components, supporting lower system size, weight, and cost. A three-level converter also converts generator output into direct current to charge the battery modules.
