N2 - This paper proposes a domino inductive power transfer (IPT) system with multiple outputs. There are two major contributions. First, a π-type compensation network is applied to achieve a load-independent feature and constant voltage output (CV). Moreover, the influence of parasitic resistances on the output voltages and system efficiency is analyzed. Second, a PCB-based repeater system without ferrite is designed, decreasing the cost and weight of the IPT system. Furthermore, a composite application of the unipolar coil and bipolar DD coils could vanish unnecessary cross-couplings. To verify this proposed topology, a PCB-based prototype with one input and five outputs is implemented. The size of the receiver and transmitter is 200 mm×200 mm. The transfer distance between adjacent outputs is 40 mm, and the switching frequency is 1 MHz. The output voltage is around 20 V when the input dc voltage is 24 V and the load resistance varies from 50 Ω to 170 Ω. The maximum efficiency of the prototype reaches 60%, showing that the proposed system could be used in practical applications.
