Free-piston linear generator (FPLG) is based on a cylindrical combustion chamber connected on the axis with a linear electric generator. The system allows the conversion of the mechanical energy produced by the combustion into electrical energy available on board the vehicle. The FREE-MOST project aims to model, simulate, control and experimentally validate a laboratory-scale FPLG configuration, w...Show More
In recent years, approximately hundred topologies have been studied for Li-ion cell balance. In this paper, some equalizer topologies, comprising classical passive and active equalizers, are considered. The comparison considered several aspects, and for each of them, different Key Performance Indicators (KPIs) were defined. The most important KPIs are related to balancing time, capacity reduction ...Show More
Electrified railways are powered by dedicated traction power substations (TPSSs) that represent nonlinear loads for the utility supply network. Power Quality (PQ) problems affect both the three-phase network that feeds the TPSS and the contact line, which completes the traction system. The goal of this study was to evaluate the harmonics generated by an 18 pulse AC/DC rectifier for railway tractio...Show More

The utilisation of solid-state circuit breakers (SSCBs) for managing large inductive loads with rated or short-circuit currents often results in overvoltage issues in the power switch, leading to potential failure. To mitigate this overvoltage, the addition of an extra electronic circuit is necessary. The main techniques typically fall into two categories: snubber-based and voltage-clamped. The sn...Show More
In this article, a novel MPPT technique is proposed and experimentally tested. It is called “grid-connected photovoltaic (PV) systems maximum power point tracking (MPPT) technique driven by the power factor correction (PFC) controller” (CICERONE). It generates, for both single stage (SS) and double stage (DS) grid-connected PV systems, the bulk voltage reference by exploiting only the internal (no...Show More
In this paper, a dynamic model of a seawater low-head turbine for an Overtopping BReakwater Energy Conversion (OBREC) system is presented. The model is not based on the physical similarity of hydraulic machines, as classical models are, and is easy to tune and lightweight to execute. These characteristics make the model ideal for preliminary control simulations or hardware-in-the-loop tests becaus...Show More
This paper proposes a methodology to evaluate the maximum power, which can be drawn out from a PV plant on the basis of its geographic location and local weather conditions. These evaluations are carried out through data analytics, starting from an experimental knowledge base, which is built through aggregation of data coming from electric characterization tests, temperature measurements and weath...Show More
