| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we focused on the load independence of the wireless power transfer circuit and examined the circuit design that can easily CV/CC charging. The analyzed circuit is a multi-resonant circuit in which the primary side and the secondary side are both series resonant. We examined a design method in which the operating frequency range of CV/CC charging is 79 -90 kHz and clarified that it cannot be realized unless the coupling coefficient is 0.298 or less. Also, the load-independent mechanism is examined, and we found that the change in the input effective power contributes and that the input power factor is always 1 for CC charging. | |
