A 44 kW wireless power transfer (WPT) system is being developed for rapid contactless charging in an electric bus in the 85 kHz band, the candidate frequency for a wireless charging system for light-duty vehicles that is currently undergoing standardization. For field operation of this WPT system using the 85 kHz band in Japan, permission for use as industrial facilities emitting radio waves is required...
Magnetic coupling occurs when magnetic field lines of an electric circuit are closing into another electric circuit. This can be an undesired effect that affects both circuits. The coupling element is mutual inductance. This paper aims to analyze the effects of inductive coupling. Coupling capacity or mutual inductance will be determined by solving the electromagnetic field issue and the effects of...
A phase memory logic module (PML module) was constructed, based on a high-temperature-superconducting core magnetic multivibrator. The phase logic is decided by the majority of multiple inputs, and therefore is similar to Parametron logic; such modules have applications in the field of neural network systems. However, the frequencies of oscillation fosc of the PML modules are not exactly the same...
