“…Therefore, it is the main limitation of increasing power capability of current IPT systems. In order to achieve high power level with a relatively lower cost, several alternatives have been proposed and developed in the past few years, like parallel topology IPT systems [16], modular-based IPT systems [12], poly-phase IPT systems [17][18][19][20][21][22][23], etc.…”

“…Although some studies on poly-phase IPT systems have been undertaken in [15,[17][18][19][20][21][22]24], the research on pad-misalignments of poly-phase IPT systems is still at its early stage and there are a lot of research problems that need to be resolved. First of all, there is no accurate mathematical model that characterizes poly-phase IPT systems, which is essential for investigating the nature of the system theoretically.…”

Bi-directional inductive power transfer (BD-IPT) systems are preferable for applications such as Electric Vehicles (EVs) and wireless integration of EVs with the utility grid (V2G). In particular, poly-phase BD-IPT systems are used in high power applications and for rapid charging of EVs but their performance is severely compromised by the cross-coupling effects between phases and the misalignment of charging pads or coils. This paper therefore presents a generalized mathematical model to investigate the cross-coupling effects caused by pad-misalignments and corresponding impacts on the power flow of ploy-phase BD-IPT systems used for EV charging. Using the proposed model, the charging behavior of an EV, based on a 3-phase BD-IPT system, is investigated under different operating conditions, analyzing the sensitivity of power flow and direction to cross coupling.Results are presented in comparison to simulations to demonstrate the accuracy of the proposed mathematical model and as well as to show that the changes in power flow and direction can be somewhat compensated for by the individual control of phases.

“…Therefore, research on power converters used in high power IPT systems becomes an important issue. Towards the aim of increasing power scalability and the overall efficiency, several attempts have been made in terms of using multiphase IPT systems [1] - [3], multi-input/multi-pickup IPT systems [4], multilevel converter (MC) topologies [5] - [7] and optimizing the efficiency [15] - [16].…”

LCL network is one of the best choices for compensating bidirectional inductive power transfer (BIPT) systems. However, H -Bridge power converter of the conventional BIPT systems generates highly distorted AC current which results in reduced overall system efficiency particularly in high power BIPT systems. In order to overcome this drawback, a multilevel converter (MC) with selective harmonic distortion (SHE) modulation method is presented in this paper to eliminate high order harmonic components in converter voltages at both sides of BIPT systems. The proposed MC topology is constructed using a modified H -Bridge converter with minimum number of power switches. The proposed topology is suitable for low to medium power applications. The simulation results demonstrate the feasibility of the proposed scheme.
