“…Several past works, including [43]- [45], have shown how the effect of manufacturing tolerances on components can cause a substantial change in the behaviour and performance of WPT systems. These effects have been mainly related to tolerances on capacitance values, but can also result from variations of self and mutual inductance values [45] due to tolerances on the electromagnetic parameters of the materials used in the construction of the system.…”

The present work aims at quantifying how, and how much, the uncertainties on the components and material parameters of a wireless power transfer (WPT) system for the static charge of electric vehicles affect the overall efficiency and functionality of the final produced device. With the aim of considering the perspective of a possible industrial developer, the parameters selected for the uncertainty quantification are chosen to be the capacitance values of the compensation capacitors and the electromagnetic material parameters used for the construction of the magnetic structure of a WPT system, i.e. the parameters of the elements to be purchased. The analysis is based on a standard system among the ones provided by the current SAE J2954 recommended practice.

The traditional wireless power transfer circuit uses the full-bridge or half-bridge inverter, which has complex circuit and control and low reliability. To solve these problems, a single-switch LC resonant circuit is proposed, which is simple in structure and can realize zero voltage switching (ZVS) without the problem of shoot-through. The circuit parameters and working process are modeled and analyzed. However, due to the influence of resonance, the common Si devices can not meet the demand because of the high blocking voltage of the switch. For this purpose, the circuit characteristics of SiC-based devices are studied, and the differences of driving and temperature characteristics between SiC MOSFET and Si MOSFET are compared. Finally, a single switch wireless power transfer (WPT) platform based on SiC MOSFET is built, which proves that SiC devices have great advantages in the field of WPT.

The equivalent resistance of the battery will change during charging in practical applications, so it is difficult to design a wireless power transfer (WPT) system with accurate constant current (CC) and constant voltage (CV) output characteristics. In addition, the WPT system efficiency is also affected by the change of equivalent resistance. Therefore, this paper studies the charging control and efficiency optimization strategy for the WPT system with dynamic loads. The WPT system with a structure of doublesided LCC compensation topology and containing controllable rectifier circuit at the secondary side is established, and the working process of full-bridge controllable rectifier circuit is analyzed. Then the output characteristics of the WPT system are analyzed. The expressions of the optimal transmission efficiency and the optimal equivalent impedance of the full-bridge rectifier are derived. The relationships between the equivalent impedance of the capacitor-filtered full-bridge controllable rectifier circuit and the phase shift angle, the charging current and the phase shift angle are also obtained. In this paper, the CC and CV charging strategies based on phase shift control of controllable rectifier circuit and efficiency optimization strategy based on dynamic equivalent impedance matching are proposed, which can improve the WPT system transmission efficiency while realizing CC and CV charging. Finally, the effectiveness of the proposed control strategy is verified by simulation and experiment. The WPT system realizes CC charging mode and CV charging mode in turn when the load resistance changes from 5 Ω to 30 Ω, and the overall efficiency is up to 90.71% at the transmission distance of 15cm.
