IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishAmong single stage, single phase, inverter configurations the Neutral Point Clamped topology is advantaged by its quiet rail switching mechanism, producing negligible common mode currents. However, it requires a double input voltage if compared with a classic full bridge inverter. A modified Neutral Point Clamped, three level, single phase, inverter topology is presented in this paper intended for Thermoelectric Generation Systems applications. The proposed topology owns an inner voltage boosting capability, thus, it can be supplied with an input DC voltage equivalent to that of a conventional H bridge inverter, or even lower. Moreover, it is able to compensate voltage drops caused by variations of the thermoelectric generator operating temperature. Finally, no extra high frequency switching devices are introduced to implement the voltage boosting function.
