High-Frequency Power Supply Lets High-Power Wireless Transmission

摘要

Mitsubishi Electric Engineer-ing Co., Ltd. has developed a high-frequency power supply technology with 3.7kW output and 6.78MHz frequency, and enables wireless transmission of high power. It adopts a new technology that enables the synthesis of output power of the four high-frequency (Class E) inverter circuits with high efficiency. Thus it enables magnetic field resonance type wireless power transmission of high power. 45-45 Solid Electrolytes to Boost All Solid-State Batteries Japanese scientists have synthesized two crystal materials that show great promise as solid electrolytes. All-solid-state batteries built using the solid electrolytes exhibit excellent properties, including high power and high energy densities, and could be used in long-distance electric vehicles.
