摘要
Various circuit topologies are possible for magnetic resonance wireless power transfer, depending on how the capacitors are connected. When using a DAB-type DC/DC converter that supports bi-directional power flow, the SP-type requires an additional inductor. This paper compares the power transmission characteristics of the SS and SP type in this setup. The power transmission efficiencies of the SS and SP types for each coupling factor show considerable similarity. In contrast, the SP-type wireless power transfer system integrated with a DAB-type DC/DC converter can provide bi-directional power transmission that is resistant to misalignment.
