Title: Yoshihiro Ikefuji: Innovator in Non-Contact Power Feeding Systems
Introduction
Yoshihiro Ikefuji is a remarkable inventor based in Kyoto, Japan, with an impressive portfolio of 40 patents. His contributions to the field of power transmission and innovative systems have marked significant advancements in technology, particularly in non-contact power feeding methods.
Latest Patents
Among his latest inventions are two noteworthy patents: the "Power Transmission Device" and the "Non-Contact Power Feeding System for Transmitting Electric Power to Power Reception Device by Magnetic Resonance." The first patent outlines a power transmission apparatus that employs a magnetic field resonance system to transmit power to a reception apparatus. This system involves the division of the output AC voltage produced by a class E amplifier, which is then supplied to a resonance circuit. The innovative design allows for the evaluation of current amplitude in the power-transmission side coil to ascertain the presence of foreign objects before executing power transmission.
The second patent enhances this concept by incorporating a detection circuit that monitors the current amplitude flowing through the transmission-side coil. If the current amplitude falls outside a predetermined normal range, it conclusively indicates the presence of a foreign object, triggering a safety response that halts power transmission.
Career Highlights
Yoshihiro has made notable contributions while working with esteemed organizations such as Rohm Co., Ltd. and Rohn Co., Ltd. His tenure at these companies has allowed him to further refine his innovative ideas and apply cutting-edge technologies in practical applications.
Collaborations
