“…Considering the approximation of the turn-off current for the LCC-connected inverter proposed in [29], the expected impedance angle θ needed to ensure ZVS is calculated as 10 • . Thus, according to the maximum and minimum reflection impedances of the system and the limitation of the current in the transmitting coil and the reflection impedance angle, we set the minimum current in the transmitting coil to 29.8 A.…”

Abstract:The effective simultaneous wireless transmission of power and information (SWTPI) is an issue of great interest. To reduce the crosstalk between power and information channels while increasing the transmission air gap and power level, we introduce an inductor-capacitor-capacitor (LCC) compensation network for an SWTPI system. First, the crosstalk between the power and information channels is analyzed. An effective parametric design method is then proposed for the LCC compensation network, which is analyzed theoretically to minimize the crosstalk. Finally, experiments are conducted at 1000 W and 115.2 kbps with an air gap of 100 cm to verify whether the proposed structure and design method of the LCC compensation network are suitable for the SWTPI.

“…In order to solve drawback of the SS compensation topology, the LCL topology is proposed in Wang et al and Feng et al, where the compensation network is determined based on the power balance and the LCT coupling conditions. Although the LCL compensation topology overcomes the high sensitivity to the coupling coefficient variation of the SS, the low design freedom still exists .…”

“…Consequently, the system can work at a constant switching frequency, and zero voltage switching (ZVS) can be achieved over a wide load range . However for conventional LCL and LCC compensation with the LCT coupling variation, the current in the primary coil remains unchanged; thus, the power transfer is proportional to the square of the coupling factor …”

“…Another approach to maintain the constant output voltage over the range of the LCT coupling variation is by carefully designing the resonant compensation network. In papers, a minimum output voltage gain variation over the specified coupling coefficient range is achieved by carefully designing the primary resonant compensation network. Similar method is presented in paper, intended to be used for the implantable cardiac pacemakers.…”

Summary In this paper, a design of the compensation network with a variable inductor is proposed, considering a wide variation of the coupling coefficient in the inductive power transfer (IPT). The characteristics of the proposed compensation network are analyzed with respect to the variable antenna coupling conditions. The realization of the zero voltage switching (ZVS) and the reactive power demand are discussed through the theoretical deduction and numerical simulation. Influence of the variable inductor on the compensation network characteristics is examined in detail, and the control algorithm for achieving the coupling independent constant output voltage is proposed. Detailed steps to design a prototype fulfilling all performance requirements are given. Verification of the proposed method was carried out on the experimental model. Recorded output voltage variation is within 5% over the wide coupling range, implying a quite well characteristic of the coupling independent voltage output. Experimental results match well with the calculations, validating the rightness of the proposed variable inductor tuning method.

“…An LCL fixed-frequency resonant topology has been proven to be suitable for supplying a steady-state track current [11][12][13][14]. And series-and parallel-compensations has been carried out to circumvent low power transfer [15][16][17][18]. However, these compensations are often studied under some isolated constraints for optimal system efficiency and less consideration of the effect of pickup coil parameters on the system.…”

A loosely coupled inductive power transfer (IPT) system for industrial track applications has been researched in this paper. The IPT converter using primary Inductor-Capacitor-Inductor (LCL) network and secondary parallel-compensations is analyzed combined coil design for optimal operating efficiency. Accurate mathematical analytical model and expressions of self-inductance and mutual inductance are proposed to achieve coil parameters. Furthermore, the optimization process is performed combined with the proposed resonant compensations and coil parameters. The results are evaluated and discussed using finite element analysis (FEA). Finally, an experimental prototype is constructed to verify the proposed approach and the experimental results show that the optimization can be better applied to industrial track distributed IPT system.
