A Method to Reduce Eddy Current Loss of Underwater Wireless Power Transmission by Current Control
نویسندگان
چکیده
In recent years, wireless power transmission (WPT) technology based on magnetic resonance has been extensively studied. However, in contrast to that the air, seawater medium will be accompanied by inevitable energy loss, is, eddy current loss (ECL), which increase with frequency and coil current. this article, an equivalent circuit model of underwater is established, two methods reduce are proposed, optimal modulus ratio for dual-coil system calculated. Electromagnetic field (EMF) simulation software verifies correctness methods, it concluded increasing phase difference or controlling ensure a certain range can effectively improve efficiency about 4~5%.

A directional-based branches current method for transmission loss allocation in the pool-based electricity market
This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

متن کاملA Short-Current Control Method for Constant Frequency Current-Fed Wireless Power Transfer Systems
Abstract: Frequency drift is a serious problem in Current-Fed Wireless Power Transfer (WPT) systems. When the operating frequency is drifting from the inherent Zero Voltage Switching (ZVS) frequency of resonant network, large short currents will appear and damage the switches. In this paper, an inductance-dampening method is proposed to inhibit short currents and achieve constant-frequency oper...
