In the absence of sources of rapidly varying field, the study of the potential distribution determined, in a linear medium, by a geometrically complex grounding may be conducted by applying the method of superposition of the effects, known as method of subareas of Maxwell. Such approach can be usefully employed in an educational tool intended for students of electrical engineering.
This paper describes lateral misalignment characteristics of electrical resonance coupling wireless power transfer (ERC-WPT) from experimental points of view. A dead zone is an important factor for ERC-WPT because ERC-WPT cannot transfer electric power in the zone. Electrical coupling units that are composed of 2 electrodes lined up laterally have a dead zone. The dead zone exists near outer edge...
Wireless Power transfer using electric field can realize highly efficient electrical power transmission and the transmission units are thin and light. However, the transmission system produces large electric field intensity and the electric field noise can make other electronic devices malfunction. A shield box is greatly effective to reduce the electric intensity 60dB without a decline of transmission...
Recently, a world is the point of need with new energy of high efficiency measures according to global climate change issues and energy shortages. [1] One of the various measures an energy control is to design and development at a precise circuit that can be used conservation and efficiency as the center with the power in industrial apparatus. High-frequency induction heat treatment industrial facilities...
The application benefits of operating stationary batteries in a partial state of charge (PSoC) can be significant. Emerging markets and applications which require dynamic cycling operation with high charge efficiency, such as, utility scale energy storage and hybrid telecommunications sites can especially benefit from this mode of operation. PSoC operation improves charge efficiency (up to 99%) and...
