| Popis: | In this paper, we study the use of Wireless Power Transfer (WPT) for feeding Electric Vehicles (EV) and other conveyance machines. We researched circuit topologies that can be extended to a bidirectional feed and are suitable as feeds for moving objects, and proposed two systems; a two-repeater coils system and a Parallel-Parallel compensation capacitor system (PP system), which are symmetrical circuit configurations on the primary and secondary side transfer. The results show that the immittance converter characteristics can be obtained by optimal design of the capacitor. Based on the power feeding experimental result, it was confirmed that the input power can be suppressed by increasing the input impedance at the time of shifting the position of the secondary side. We demonstrate the usefulness of the two-repeater coils system and PP system, assuming the use of multiple ground coils. |
