Abstract

Distributed generation (DG) is increasing its role in modern power systems and the electricity produced by unconventional a.c. and d.c. sources is becoming fundamental in the overall balance. A key element of DG is its mix of different power sources, mostly connected with the grid trough power converters. Since the latter introduce grid perturbations and, at the same time, are affected by the instantaneous grid status, new topologies are being proposed aiming at reducing mutual influences, thus improving the overall efficiency, behaviour and cost. Since cascaded multilevel converters offer significant advantages over the widely diffused PWM two-level converters in terms of harmonic mitigation and low switching frequency, in this chapter a 9-level cascaded inverter suitable for distributed generation and supplied by four fuel cell stacks is proposed and discussed. Such a system operates both in grid-connected and in stand alone mode controlled by a fuzzy logic controller implemented on a FPGA. After a detailed description, system performance are verified and analysed through simulation and experimental results.
