要約(英語): A wireless power transfer (WPT) technology has recently garnered significant attention owing to its advantages of removing wire and mitigating charging concerns. In a conventional resonance-based compensation circuit design, the power transmission characteristics strongly depend on the coupling condition of the transmitter and receiver coils. Therefore, some non-resonance-based designs have been proposed. However, they are complicated and lack the resonance condition; therefore, circuit designers cannot comprehensively understand their power transmission characteristics. This study proposes a visualization method for the power transmission characteristics based on a divided analysis of WPT systems. The proposed visual map, which consists of simple circles and lines, can help in intuitively understanding the tendency of WPT and evaluate the transmission power of the compensation circuits, including the non-resonance condition. The tendency obtained from the visual map was validated via numerical simulations and experiments. The experimental results were significantly consistent with the intuitively estimated tendency and the evaluated power transmission.
