| Abstract(in English) | Capacitive coupling WPT is keenly expected to work for automatic guided vehicles (AGV) in motion. However, a serious problem is increasing electromagnetic field leakage due to increasing in transmission power. The purpose of this report is to suppress that from the TX electrode for capacitive coupling WPT. As a result of electromagnetic simulation with simplified AGV model, it is shown that the leakage is small when the vehicle is near the power source of the TX electrode. It is also shown that the electromagnetic field can be suppressed by designing the load impedance $Z_{rm{L}}$ to the optimum value. We measured the electromagnetic field by changing $Z_{rm{L}}$ with a simplified AGV model. As a result, the electric field was suppressed to $65.7~%$ and the magnetic field was suppressed to $62.6~%$ compared with conventional $Z_{rm{L}}$. |
