PV converters: step-up inverter
The system consists of three dc/dc boost converters with a common point and operating as a three-phase inverter with intrinsic step-up capability. The converter obtained can invert, amplify and, where possible, regenerate bidirectional power sources such as fuel-cells, small gas turbines and photovoltaic arrays. There are two main advantages to the system: the use of only six IGBTs and small passive elements, and the fact that it does not need reverse voltage blocking capability.

PV converters: transformerless converter
The research has been focused on transformerless photovoltaic inverter topologies for three-phase grid connection with the main focus on the safety issues that result from the lack of galvanic isolation. A common-mode model, valid at frequencies lower than 50kHz, is adopted to study the leakage current paths.

Anti-islanding algorithms
The research has been started with a deep simulation and experimental comparison of the passive and active methods used for islanding detection. Then the research has been carried out on Kalman-filter-based and wavelet-based methods for islanding detection
The research developed in cooperation with a visiting reasercher from Spain has originated the following project “Algoritmos para la detección de la condición de isla eléctrica en inversores aplicados a sistemas de generación fotovoltaica distribuida de acuerdo con la normativa europea” Coordinatore Víctor M.
