With a total of 11 patents to his name, Itoh's work reflects a commitment to enhancing the efficiency and performance of electric systems.

Latest Patents

One of his latest patents is a control device for an alternating current motor. This innovative device includes a target current generating unit that produces a current order value based on a torque order. It features a current detection device that detects the alternating current supplied to each phase of a polyphase alternating current motor. Additionally, a coordinate transforming unit converts the detected alternating current into d-axis and q-axis currents. The vector control unit then performs current feedback control to ensure that the d-axis and q-axis currents follow their respective target currents.

Another significant patent is for a brake system designed for electric vehicles. This system addresses the uncomfortable vibrations that can occur during regenerative braking. By gradually increasing the regenerative braking force from a previously set initial value to the demanded braking force, the system prevents sudden load variations that cause vibrations. If the demanded braking force exceeds a regenerative acceptable value, the system ensures that the regenerative braking force does not surpass this limit, compensating for any deficiencies with hydraulic braking.
