Control of Fuel Cell Power System

Abstract

In recent years, it is getting attention for renewable energy sources such as Fuel Cell (FC), batteries, ultracapacitors or photovoltaic panels (PV) for distributed power generation systems (DG) or electrical vehicles. This paper proposes a DC/DC converter and DC/AC inverter scheme to combine the Fuel Cell Stack (FC). The power system consist of a FC stack, a DC/DC converter, inverter and load. A FC mostly could not produce necessary output voltage, the DC/DC boost converter is used for obtaining the desired output voltage. The inverter is used for many applications such as electrical vehicles (EV) and distributed generation systems (DG). In this paper, sinusoidal pulse modulation technique and space vector pulse width modulation technique have been simulated and compared for electrical vehicles applications.
