“…Unlike the frequency-domain small-signal model [17], the model proposed in this work exposes the presence of the non-minimum-phase dynamics such that instability due to the RHP zero can be avoided via proper design. As compared to the time-domain large-signal model [18], this work features model-based compensator parameter design and simpler stability assessment, which facilitates a better understanding of closed-loop stability.

In wireless power receiver systems, the buck converter is widely used to step down the higher rectified voltage derived from the wireless receiver coil, to a lower output voltage for the immediate battery charging process. In this work, the presence and effect of the right-half-plane (RHP) zeros found in the smallsignal inductor-current-to-duty-ratio and output-voltage-to-dutyratio transfer functions of the buck converter in the wireless power receiver system on the control performance, are investigated. It is found and mathematically proved that the RHP zeros are introduced by the current source nature of the system attributed to the series-series compensation and finite DC-link capacitance. The RHP zero not only results in non-monotonic open-loop dynamic response but also complicates the design of feedback control and causes potential closed-loop instability. Theoretical and experimental results are provided to validate the presence of the RHP zeros and their effect on open-loop and closed-loop dynamic responses.

Unlike the plug-in charging system, which has safety concerns such as electric sparks, wireless power transfer (WPT) is less-time consuming, is environmentally friendly and can be used in a wet environment. The inclusion of hybrid energy storage systems (HESSs) in electric vehicles (EVs) has helped to increase their energy density as well as power density. Combined with static wireless power transfer, a WPT–HESS system is proposed in this article. The HESS system includes a battery and supercapacitor (SC) connected to a WPT system through DC–DC converters. To ensure a stable DC bus voltage, an inductor–capacitor–capacitor series (LCC-S) compensation network has been implemented in the WPT system. Utilizing the two-port network theory, the design equations of the LCC-S compensation network are derived in order to realize the maximum efficiency point for the WPT system. To ensure that the WPT system operates at this maximum efficiency point and that the SC is charged to its maximum capacity, an energy management system (EMS) has been devised that generates reference currents for both the SC and battery. An integral terminal sliding mode controller (ITSMC) has been designed to track these reference currents and control the power flow between the energy storage units (ESUs) and WPT system. The stability of the proposed system is validated by Lyapunov theory. The proposed WPT–HESS system is simulated using the MATLAB/Simulink. The robustness of the ITSMC against the widely used proportional–integral–derivative (PID) and sliding mode controller (SMC) is verified under abrupt changes in the associated ESU resistance and reference load current. Finally, the simulations of the WPT–HESS system are validated by controller hardware-in-loop (C-HIL) experiments.

This study presents a novel wireless power transfer (WPT) system structure that transmits electrical energy from a fuel cell (FC) stack integrated with a quadratic boost converter (QBC). The main objective of the proposed study is to provide a high voltage conversion QBC based WPT system to transfer power from a low voltage FC energy unit. To adjust the power flow from the FC unit with nonlinear production behavior, a pre-regulating WPT system is developed with QBC located on the transmitting side. Besides, the design procedure of the system with analytical equations is expressed in detail. To validate the viability and effectiveness of the proposed WPT system, a 100 W proof-of-concept model is developed with Horizon H-100, and analyzed for different case studies, including dynamic operating and loading conditions. The constructed WPT system is performed for 80%, 90%, and 100% loading situations. At full loading, the performance results show that the load-side consumes power in the rating of 77.8 W while the FC power source generates approximately 93.1 W. In this case, the efficiency of the system corresponds to 83.6%. Besides, the efficiency of the complete system is analyzed under various operating conditions.
