The interest in hybrid electric vehicles (HEV) is growing, not only because of environmental impact in the transportation sector, but also because they are becoming economically attractive regarding the cost of driving and maintenance when compared to internal combustion engine. The use of PEM fuel cell (PEMFC) as a main source of HEV can represent the future of the automotive industry. The link between the fuel cell and the electric motor is made by a DC/DC converter and a three-phase inverter.

L'interesse per i veicoli ibridi elettrici è in crescita, non solo a causa dell'impatto ambientale nel settore dei trasporti, ma anche perché sono economicamente interessanti per quanto riguarda i costi di guida e manutenzione rispetto al motore a combustione interna. L'utilizzo della pila a combustibile di tipo PEM come principale fonte dei veicoli ibridi elettrici può rappresentare il futuro dell'industria automobilistica. L’interfaccia tra la cella a combustibile e il motore elettrico è costituito da un convertitore CC/CC e da un inverter trifase. In questo lavoro, viene presentato il convertitore “Multidevice interleaved boost converter (MDIBC)” che è responsabile di aumentare e regolare la tensione dal PEMFC al DC-link. Il convertitore proposto è confrontato con altre due topologie di convertitori: il “Interleaved boost converter (IBC)” e il “Multidevice boost converter (MDBC)”. Per le tre topologie, le equazioni del modello di segnale piccolo e il design della strategia di controllo a doppio loop sono dimostrate e illustrate utilizzando MATLAB e Simulink.

Abstract
The interest in hybrid electric vehicles (HEV) is growing, not only because of environmental impact in the transportation sector, but also because they are becoming economically attractive regarding the cost of driving and maintenance when compared to internal combustion engine. The use of PEM fuel cell (PEMFC) as a main source of HEV can represent the future of the automotive industry. The link between the fuel cell and the electric motor is made by a DC/DC converter and a three-phase inverter. In this work, it is presented a unidirectional multidevice interleaved boost converter (MDIBC) which is responsible to increase and regulate the voltage from the PEMFC to the DC-link. The proposed converter is compared to other two converter topologies: the interleaved boost converter (IBC) and the multidevice boost converter (MDBC). For the three topologies, the equations of the small signal model and the design of dual loop control strategy are demonstrated and illustrated using MATLAB and Simulink.File | Dimensione | Formato | |
