Abstract
In inductive power transfer (IPT) systems, series–series (S-S) and double capacitances and inductances–series (LCCL-S) compensation topologies are widely utilized. In this study, the basic characteristics of S-S and LCCL-S are analyzed and compared in the tuning state. In addition, considering the universality of detuning, and because the two topologies have the same secondary structures, the voltage and current stress on components, input impedances, voltage gains, and output powers of S-S and LCCL-S are mainly analyzed and compared in the detuning state, which is caused by variations in the secondary compensation capacitance. To compare the efficiency of the two topologies and verify the comparative analysis, comparative experiments based on a 2.4-kW IPT experimental prototype are conducted. The comparative result shows that the S-S compensation topology is more sensitive to load variations and less sensitive to secondary compensation capacitance variations than LCCL-S. Both in the tuning and detuning states, the efficiency of the S-S topology is higher in high-power electric vehicle (EV) applications, and the efficiency of LCCL-S is higher in low-power.
Highlights
To solve the environmental pollution problems and ensure the continuous reduction of traditional energy usage, new energy industries have emerged, and are being developed rapidly, especially in the electric vehicle (EV) industry [1,2,3]
The output power of the S-S topology increases as the load increases, but in the LCCL-S topology, the output power increases as the load decreases
LCCL-S presents a constant-voltage source characteristic to the load, and the maximum efficiency is achieved under the low-output-power condition
Summary
To solve the environmental pollution problems and ensure the continuous reduction of traditional energy usage, new energy industries have emerged, and are being developed rapidly, especially in the electric vehicle (EV) industry [1,2,3]. In [15], under the condition of mutual inductance variations that are misalignment, the S-S and double-sided LCC topologies are compared in terms of output power, caused by voltage, misalignment, the S-S and double-sided. During actual operation, because of high temperatures, oscillations, leading to a large drop errors, in the mutual inductance (coupling coefficient) minor variations in the device manufacturing and some other physical factors, actual and parameters During actual operation, because of high temperatures, oscillations, capacitances and inductances) may differ from designed parameters Both detuning reasons may device manufacturing errors, and some other factors,topologies actual parameters There are few studies on detuning have the same series structures in a secondary loop, the characteristics of S-S and LCCL-S are that is caused by tuning deviations compensation components. Efficiencies of S-S and LCCL-S by performing calculations and simulations, a 2.4-kW experimental prototype is configured to compare the efficiencies of S-S and LCCL-S compensation topologies
