Broadband Power Converter for Wireless Power Transfer System via Coupled Magnetic Resonances
摘要
Abstract
Broadband power converter for wireless power transfer system via coupled magnetic resonances was designed in this paper, the performance of power converter which adopts class-E amplifier was analyzed, the efficiency and the load power were improved by optimizing the working states and matching network. Combining the design of matching network of transmitter and receiver resonator, this paper optimizes broadband characteristics of system and analyzes transmission characteristic for various resonant frequencies and resonators. Finally the experimental analysises which are in 0.15~8MHz broadband at 30cm are carried on to verify the theory and simulation, power converter maintains higher system efficiency in wideband working condition.关键词
