Abstract

Dynamic response, lack of efficient power transfer, and high response time resulting in increased losses and reduced minimal efficiency are the major issues of the existing controls in the wireless power transfer (WPT) for EV charging applications. Model predictive (MP) control can handle several constraints and disturbances by predicting the future behavior of the system and generating control signals accordingly, making the system stable, and operating at high efficiency. This work proposes transmitter-side model predictive (MP) control for the three-level T-type inverter–based wireless EV chargers. The prime focus of this article is attaining remarkable efficiency and offering CC/CV charging for the EV battery. The validation of the proposed MP control is carried out with a 3.3-kW laboratory model. The steady-state behavior and dynamic performance under sudden changes in the load and misalignment (vertical and horizontal) were studied in detail. The results provided validate the effectiveness of the proposed MP control.

基于模型预测控制的发射机侧变换器控制无线电动汽车充电系统最大效率跟踪

动态响应、缺乏高效的电力传输以及响应时间过长导致损耗增加和最低效率降低是现有电动汽车充电无线电力传输（WPT）控制系统存在的主要问题。模型预测（MP）控制可以通过预测系统的未来行为并产生相应的控制信号来处理多种约束和干扰，使系统稳定，并以高效率运行。本文提出了基于三电平t型逆变器的无线电动汽车充电器的发射端模型预测控制。本文的主要焦点是实现卓越的效率，并为电动汽车电池提供CC/CV充电。通过3.3 kw的实验室模型验证了所提出的MP控制。详细研究了在载荷突变和（垂直和水平）不对中情况下的稳态性能和动态性能。结果验证了所提出的MP控制的有效性。
