N2 - To meet the charging requirements of constant current output (CCO) and constant voltage output (CVO), and maintain constant output when the couplers are misaligned in inductive power transfer (IPT) system, a hybrid three-coil IPT topology with high misalignment tolerance is presented. Two mode conversion switches, one inductor and two capacitors are added on the receiver side of the conventional series series (SS) topology to realize the switching SS and S/LCC topologies, so as to achieve the CCO and CVO. The system combines all the advantages of the two topologies, does not need to switch frequency, and has simple control. Moreover, it gets rid of the wireless communication between the receiver and the transmitter. The transmitter adopts two coils connected in reverse series to improve system's misalignment tolerance. The operating principle of the topology is introduced in detail, and the main idea of parameter design is also given. Ultimately, a 100W experimental prototype is built to verify the effectiveness and superiority of the proposed hybrid IPT topology.
