Transmitter-Side Converter Controlled Wireless EV Charging System Tracing Maximum Efficiency Using Model Predictive Control

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.
