Challenges for the Goal of 100% Renewable Energy Sources to Fit the Green Transition
The increasing penetration of Renewable Energy (RE) into the electrical market is desirable in terms of sustainability. Nevertheless, it is a challenge that all the interested actors shall address from both the technical and economical points of view. This paper provides an overview of the main challenges and solutions towards the technological transition to an electrical system with 100% renewable energy sources in terms of innovations and operative limits of the traditional systems. These innovative paradigms will also address the social impact and government policies.
Design and Validation of a Dynamic Inductive Power Transfer System for EV Battery Charging
In this paper, a Dynamic Resonant Inductive Power Transfer (DRIPT) System for the Electric Vehicle (EV) battery charging is proposed. In particular, the aim of the work is the general design of the whole system and its validation, with particular attention to the power electronic converters and their control. For the transmitter side, a DC/AC converter is used. It is controlled through the phase-shift technique and supervised by a Zero Phase Angle detection algorithm to ensure the maximum power transfer. For the receiver side, a double conversion stage, consisting of a diode rectifier and a controlled buck converter, is provided. The system is then simulated to verify its proper design.
Magnetic field effects on human body of wireless chargers for E-bikes
For the electric vehicles battery charging, the wireless power transmission is increasingly representing an innovative solution. The inductive power transfer is the standard technology of wireless charging: the energy transfer occurs between two magnetically coupled coils. Although this battery charging system is especially convenient for E-bikes, the physiological effects of the related magnetic fields shall be estimated and taken into account. In this paper, a 200 W prototype of wireless battery charger for E-bikes is proposed and described. Moreover, various measurements of the surrounding magnetic field are carried out to evaluate the actual physiological compatibility of the system.
