| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Research on magnetic coupled wireless power transfer with resonant circuit has been researched for a long time. Research on efficiency improvement and voltage stabilization in the steady state was continued, and a lot of knowledge was accumulated. On the other hand, in the WPT technology, which requires a resonant circuit configuration, there are still few analyzes during transients. In particular, the voltage of the resonant capacitor undergoes a large amplitude change under the design conditions even in a steady state. The ratio of amplitude between steady time and transient time varies depending on design specifications and usage conditions. In magnetic coupled WPT, extremely diverse and complex transient phenomena occur due to changes in input voltage, load, coupling factor, control signal, and so on. In this paper author analyze the behavior of the capacitor voltage when the input voltage is applied in the N-S and S-S types. Along with the acquisition of the measured waveform, the behavior is analyzed by using the analysis by linear circuit. And voltage estimation and points to keep in mind during transients in practical circuits are considered. | |
