要約(英語): Inductive power transfer (IPT) systems suffer from power loss caused by reactive currents that circulate in the system during soft-switching operation. To address this problem, this paper proposes a novel soft-switching active-bridge (SAB) converter. The SAB converter comprises a full-bridge active (FBA) converter and an LC circuit connected to the one-side leg. This composition suppresses the reactive current circulating between the resonant network and the switching devices. The experiment conducted to compare the proposed converter with a conventional one shows that the efficiency of the IPT system with the SAB converters could be maintained high over a wide operation range. Furthermore, an efficiency improvement by 1.3 pt to the general IPT system could be achieved at 3.3kW-output.
