“…The active rectifier control is based on a phaselocked method for the output current/voltage. Researchers in [107] proposed a strategy for semi-impedance-matching under large load variations conditions. The strategy is based on properly selecting full-bridge and half-bridge modes of the inverter and rectifier.…”

Inductive power transfer (IPT) for Electric Vehicles (EVs) is an emerging technology that can transfer power wirelessly over certain distances, thus offering some remarkable characteristics in terms of flexibility, position and movability. The output power of an IPT system depends on the coupling factor of the magnetic couplers which can deviates from the nominal operating conditions due to occurrence of misalignment. Nevertheless, misalignment of the magnetic couplers in inductive charging is inevitable, and it usually results in the variation of the mutual inductance and output power of the system with corresponding decrease in the system overall efficiency. So far, the literature has reported various techniques for achieving designs with higher misalignment tolerance. The reported techniques can be mainly classified into three categories, as viewed from the following aspects: magnetic couplers layouts, compensation networks and control strategy. Each of these techniques has its pros and cons in terms of implementation cost, system layout, efficiency, power density and reliability depending on the application. With the increased investigation of more applications of IPT, new modified techniques of improving the misalignment tolerance in the IPT system are continuously being proposed based on permutations and combinations of the existing ones; thus causing some confusion and difficulties for researchers and system vendors to follow. This paper, therefore, aims to provide a comprehensive review of the existing methods for IPT systems that address the misalignment issue in EVs wireless charging. A review of the IPT system is presented and an investigation of the numerous factors affecting the output power and performances of the system when the coils are not aligned. In addition, the advantages and disadvantages of each technique on the IPT system's performance are analyzed in detail.

“…This method has a number of drawbacks, including increased additional power losses and complexity owing to the secondary components. PV can be obtained through inverter side controlling like optimal-redundant state-selection [17], [18], when a passive MLR without PWM is utilized; nevertheless, as earlier stated, PV cannot be assured at particular operating situations at N>3 [19], [20]. Furthermore, Optimal-Redundant state selection may degrade MLI-based performance by restricting switch-state selection freedom, increasing switching losses, and degrading the quality of output voltage, where redundant switching states were employed for PV rather than output waveform determining) [21].…”

A closed-loop auto-tuner proportional integral derivative (PID) controller for tuning the DC-link voltage, voltage neutral controllers, and DQ axis current for a power factor corrector with Vienna rectifier is developed and discussed in this study. In traditional tuning of these control loops, it is needed to tune one loop at a time manually, which tends to be a difficult and time-consuming process. In this work, we add a closed-loop PID auto-tuner in the control design will help to simplify and speed up this process by tuning all the 4 PID controllers in a single simulation running in a closed loop. Essentially, it runs auto-tuning experiments for the DQ axis -current, output voltage, and neutral point voltage loops by injecting perturbations; recording the output; estimating the plant frequency response, and tuning the PI controller parameters. In DQ-axis control, projections are used to convert time-based3-phase currents into a time invariant 2-coordinate vector. The results after adding the auto-tuner show that the response time improved considerably when the balanced load was introduced with the individual loads being connected. The results show that the neutral point voltage controller did a good job of keeping the voltage neutral point stable compared to the older controller gains.

“…To simplify the control, a frequency-and voltage-tuning method and an onoff-key modulation method are proposed to achieve the two goals by controlling the power converter on the transmitting side only [16,17]. Additionally, a semi-impedance-matching control scheme is proposed in [18] by selecting the fullor half-bridge operating mode of the converters on the double sides without complicated control.…”

To eliminate the plug-in/out actions for automatic wharves, a splitting-coil-based inductive power transfer (IPT) system is proposed to improve transfer efficiency for reefer container wireless charging. Firstly, the power requirement of a reefer container only hits a few operation points and each operation point is in correspondence to an individual resistance point (IRP); secondly, the maximum efficiency of an IPT system can be achieved with the optimal load resistance (OLR). Therefore, the system efficiency can be improved by transforming the OLR into or near the IRPs. The idea of this work is to create double OLRs of the system by altering the splitting coils operating in parallel mode or series mode with switches, then to select the proper OLRs to match the IRPs for efficiency improvement. A 0.54 kW prototype was built to validate the performance of the proposed approach. The results indicate that with the proposed method, the system can maintain the system efficiency >90.7% from 14 Ω (0.54 kW) to 60 Ω (0.13 kW), with an improvement of 7.0% at most compared with that of the system without the optimisation in the same load resistance range.
