title = "Investigation of a Multi-Modular IPT System on the Efficiency and Current Balancing due to Inter-/Cross Coupling",
abstract = "Inductive power transfer systems can process higher power using multiple charging pad modules connected in parallel. However, the effects on the system operation of the inter-/cross coupling among the pads have to be studied. This paper analyses the power transfer efficiency and current distribution of a quadruple modular IPT system. Additionally, a sensitivity analysis of the power transfer efficiency is provided based on the tolerances of the secondary resonant capacitors. The analysis shows that the efficiency of a multi-modular IPT system will increase compared to a single module and that there would not be a negligible imbalance in the current due to the inter-/cross coupling. In the experiments, the results of the quadruple modular IPT system's estimated AC efficiency are lower than a single module. It also shows that the could be bifurcation when multiple modules are deployed. Both can be attributed to the mismatch in resonant frequency, self-inductance and main mutual inductance between the modules. Future work will focus on mitigating the circulating currents caused by the mismatch between modules.",
