The proposed onboard wireless charger is new with respect to the kind of onboard AC/ DC topologies used with the receiver unit. It is based on the cascade connection of two-phase interleaved boost converter and full bridge resonant circuit. It offers wide range control of voltage gain and also bears higher efficiency due to single stage power conversion for the received power. Due to superior efficiency, constant current operation and high performance under misalignment conditions double sided LCC compensation has been used for the resonant tank. This topology also saves number of active switch count by sharing of switches between the two-phase boost converter and full bridge resonant circuit. Also, there is no need of isolation of receiver coil during the discharging of the EV battery due to use of LCC compensation. The proposed charger topology is simulated using MATLAB simulation platform to validate the charge/ discharge operation of the wireless charger and also a scale down prototype is built to verify these functionality.

In recent years, we have observed an increased volume of proposals for Internet of Health Things (IoHT) applications in the literature. Developing this type of application takes work, as it involves a series of challenges, many of them related to the constant change in the context of these applications, such as challenges related to energy consumption, the type of network communication, and its latency. In this sense, the development of self-adaptive systems is an alternative that has been explored for these applications. Self-adaptive systems can adapt to changes in context automatically, changing their behavior. However, developing self-adaptive systems is not trivial since, unlike other systems, they must be designed to evolve and adapt their behavior at runtime continuously. In this sense, we propose a Kotlin framework for developing self-adaptive IoHT applications for Android mobile devices called KREATION. This framework was developed using the Model-View-control architecture and incorporates the MAPE-K adaptation loop into its internal logic. It also presents mechanisms to help collect data from Android smartphone sensors and data from the Google Fit API, which allows you to obtain data collected from other Android devices, such as smart bands and smartwatches. We evaluated the framework using it to develop two proofs of concept demonstrating that it is functional and can help the development of self-adaptive IoHT applications.

Generally, the output voltage of a PWM inverter that drives SPMSM (Surface Permanent Magnet Synchronous Motor) has many harmonic components caused by switching. Harmonic components cause EMI (Electro Magnetic Interference), noise and leakage current problems. LPF (Low Pass Filter) including LC filter is effective to suppresses harmonics. LC filters have the potential for resonance phenomena. In addition, because of the presence of two dynamics, multivariable control based on modern control theory is required. Stable control is possible for SPMSM with Active LC filter, using ILQ (Inverse Linear Quadratic) control, which can realize robust multivariable control, and the IRM (Inverse Reference Model), which is two-degree-of-freedom control system. In this paper, Simulations confirm the effectiveness and robustness of the active LC filter. controlling the SPMSM with active LC filter by this control method can suppress harmonics and contribute to the improvement of EMI problems and noise.
