Abstract

Since the magnetic resonant coupling was suggested for wireless power transfer (WPT), the theoretical analysis and experimental verification of resonant coupling structures have been investigated. However, the relationship between the performance characteristics and the load conditions has not been fully explored yet. In this research, a magnetic resonant coupling wireless power transmission system is theoretically analyzed and simulated under different load conditions. The transmitting circuit is constant and receiving circuit is changeable. The load conditions making power efficiency at center frequency over 50 percents has been found out. Then, the experiment results are obtained to support above.
