“…However, using a passive full bridge rectifier entails energy losses, thus reducing the power efficiency. With the aim to reduce the energy conversion losses, the solution of a direct AC-DC boost converter (active full bridge) can be adopted [38,39].…”

Magnetostrictive alloys are very promising for Vibration Energy Harvesting applications to supply power to Wireless Sensor Network (WSN) and Internet of Things (IoT) devices, especially because of their intrinsic robustness. Typically, vibration energy sources are random in nature, usually providing exploitable voltages much lower than the electronic standards 1.6, 3.3 and 5 V. Therefore, a Power Electronic Interface (PEI) is needed to improve the conversion to DC output voltage from AC input over a wide range of frequencies and amplitudes. Very few or no conversion techniques are available for magnetostrictive devices, although several have been presented over the years for other smart materials, such as piezoelectrics. For example, hybrid buck–boost converters for piezoelectrics use one or more external inductors with a high-frequency switching technique. However, because of the intrinsic nature of harvesters based on magnetostrictive materials, such energy conversion techniques are proved to be neither efficient nor applicable. An improved AC–DC boost converter seems very promising for our purpose instead. The key feature is represented by the direct exploitation of the active harvester coil as a storage element of the boost circuit, without using other passive inductors as in other switching methods. Experimental tests of such a converter, driven with a real-time operating Arduino controller to detect the polarity of the input voltage, are presented with the aim to assess the potentiality of the scheme with both sinusoidal and impulse-like inputs. Simulations have been performed with LTspice, and the performance and efficiency have been compared with other energy conversion techniques.

“…Li et al [34] proposed a ferro-nickel (Fe-Ni)/PZT H-type fork magnetoelectric composite structure with a high quality value and energy management circuit for harvesting. Iannone et al [35] connected the magnetostrictive harvester to an AC-DC boost converter. Based on the simulation results, the proposed circuit was proven to increase more output voltage than that induced by the magnetostrictive harvester.…”
