M.S. Theses (Tesi di Laurea Magistrale)


Title: FPGA based control of a fuel cell interface converter

Content: the control system for a step-up dc-dc converter, based on the coupled inductor interleaved boost topology, has to be designed and implemented. The converter operates as the front-end stage of the interface between a fuel cell and a micro-grid. This calls for accurate input currrent control and suitable power management strategies. Both can be effectively implemented digitally, thanks to a rapid FPGA design kit based on Labview.

Expected developing time: six-seven months (two for theoretical analysis and simulations; three-four for experimental setup and measurements; one month for writing).

Tutor: Simone Buso


Title: Digital control of a battery charger-discharger for micro-grid applications

Content: energy storage is considered a key component of any micro-grid. Management of batteries requires suitable control algorithms driving the interface converter, so as to maximize lifetime and reliabiltiy. The implementation of such algorithms on a digital control platform is the main objective of the thesis. The controller will be designed and tested using Labview and the general purpose inverter controller (GPIC) board.

Expected developing time: six-seven months (two for theoretical analysis and simulations; three-four for experimental setup and measurements; one month for writing).

Tutor: Simone Buso


Title: Design and Implementation of an Energy Harvesting Circuit for a Self-Powered Switch

Content: self-powered switches are becoming commercially available for energy-free building automation and wireless control. Objective of the thesis is the development of an energy harvesting circuit for a commercial self-powered switch. Activities include a preliminary characterization of the device, successive design of a circuit solution for improved energy extraction, and experimental prototyping and testing of the developed harvesting circuit.

Expected developing time: six-seven months including experimental testing.

Title: Digital Control of a Magnetically Coupled Ćuk LED Driver

Content: the thesis focuses on the FPGA implementation of a digital controller for a LED driver based on the magnetically coupled Ćuk topology. The target control strategy is to be simulated using Matlab/Simulink/PLECS, and successively VHDL-coded on an Altera FPGA development board. The digital controller is then to be tested on an existing 40V, 1A LED driver prototype. Upgrading of the existing prototype according to the developed technique is expected as part of the thesis.

Expected developing time: six-seven months including experimental testing. A 40V, 1A LED driver prototype already exists.

Title: Inrush current limitation in grid connected rectifiers

Content: this thesis aims at investigating the inrush currents that occur in grid-connected rectifiers due to the charge of electrolytic filter capacitors. Passive as well as active inrush current limitation techniques have to be investigated by theoretical analysis, simulation and experimental measurements.

Expected developing time: six months (theoretical analysis and simulations: two months, experimental setup and measurements: three months, writing: one month).

Title: Isolated LED lamp using a resonant LLC converter

Content: in this thesis, a LED based electronic ballast using a resonant LLC converter has to be designed and tested. The work concentrates on the lamp current control with the goal of maximize the dynamic performance when PWM dimming is used. A first power stage prototype, rated at 150 W, is already available.

Expected developing time: six months (theoretical analysis and simulations: two months, experimental setup and measurements: three months, writing: one month).
