| Abstract(in English) | Research on magnetically coupled wireless power transfer with resonant circuits has been carried out for a long time. In the research process of nearly 30 years, it has become an even bigger trend in recent years. In particular, a lot of knowledge has been accumulated in improving efficiency and stabilizing load voltage and current. In order to increase the transmission distance, which is a benefit, mechanisms and technologies have been accumulated that enable high efficiency and good power supply quality up to the coil size. On the other hand, to allow the variable distances and positions between power transmission and reception coil, active control by inverters and converters on the power transmission and reception side, variable capacitance control, etc. are required, and increasing the system size and cost is an issue. The transmission distance and misalignment are unified and reflected in the coupling factor k. The change in load can correspond to the change in equivalent resistance R. The construction of a mechanism that allows large changes in k and R without active control is still under development. The author has already found an effective means for the load voltage to have "Inverted V-shape" characteristic in the optimized design of the S-SP type. By applying this design method, it was confirmed that a large displacement in the triaxial direction can be tolerated when both the primary and secondary coils are square. This time, as a result of further verifying the wireless power transfer system using rod-shaped coils for both primary and secondary, good performance was demonstrated. |
