Special Issue Information

Dear Colleagues,

The conversion of renewable energy sources into electrical energy and the relative storage is of fundamental importance in the modern world. In recent years, great research attention has been paid to such topics. Very different renewable energy sources can be exploited, with examples including solar energy, wind energy, vibration kinetic energy, thermal energy, electromagnetic field energy and so on. Moreover, renewable energy systems can range from large-scale power generation (kW to MW, such as in the case of wind turbines or photovoltaic plants) to low-power energy harvesting systems (mW to W, such as vibration energy harvesting in backpacks or thermal energy harvesting units). With such a great variety of applications and power ranges, a renewable energy system always needs power electronic circuits and proper control techniques for the optimal conversion into electrical energy of the primary source and for the storage of the converted energy into batteries or supercapacitors. The design and optimization of such circuits and techniques is of crucial importance for the optimal exploitation of the renewable energy source, thus avoiding the waste of precious energy that unavoidably leads to unnecessary oversizing of the entire system and results in increases in weight, volumes, and costs. Therefore, the goal of this Special Issue is:

To focus on the latest scientific results and advances in the analysis, the design and the optimization of power electronic circuits and techniques for the conversion and storage of renewable energy sources;

To bring together scientists adopting several approaches and working on the above topics;

To promote and share as much top-level research in the field of power electronic circuits for renewable energy systems as possible.

This Special Issue is open to both original research articles and review articles covering (but not limited to) the analysis, the design and the optimization of power electronic circuits for the conversion and storage of the following renewable energy sources:

  • Photovoltaic sources;
  • Vibrations (piezoelectric, electromagnetic, electrostatic and magnetostrictive harvesters);
  • Wind turbines;
  • Thermoelectric generators;
  • Regenerative suspension systems (automotive and railway applications);
  • Other innovative energy harvesting systems (rainfall, electromagnetic fields, pyroelectric, bistable systems for satellite applications).

Electromechanical energy harvesters are used to extract energy from vibrations occurring in nature, transport, or industry. The main problem with such solutions is that their output voltage is completely dependent on the frequency and amplitude of the vibrations, which can make it difficult to power a specific device or charge a battery. Therefore, it is necessary to use solutions that meet these requirements. Most harvesters contain additional, specialized mechanical gearboxes, called mechanical rectifiers or power electronic interfaces, used to match the harvester’s output voltage to the load. Design work was carried out, the construction of the proposed energy harvester was described, and the operation principle of the author’s control algorithm was presented. The results of the research confirm the possibilities of influencing the output voltage and power of the harvester system independently of the frequency and excitation amplitude. Full article

A self-supplied circuit that is able to significantly increase the power delivered to a bridge rectifier by a Resonant Piezoelectric Vibration Energy Harvester (RPVEH) is presented and discussed. The proposed circuit, called the Energy Harvester Power Optimizer (EHPO), is implemented by means of a switch-mode converter that emulates a negative capacitance. Unlike switch-mode impedance emulators, based on sophisticated tracking algorithms requiring lossy microcontrollers, EHPO exploits a very light control circuit based on a hysteresis comparator. The EHPO is self-supplied since it does not need an external supply, but it draws the energy for its operation directly from the RPVEH. Moreover, it is developed without the assumption of purely sinusoidal vibrations. Experimental results show that the EHPO can significantly increase the power delivered to a rectifier, both in the case of sinusoidal vibrations (percent gain of the net extracted power up to about 190%) and non-sinusoidal vibrations (percent gain of the net extracted power up to about 245%), regardless of the shape of the forcing acceleration and regardless of the RPVEH resonance frequency.
