AC-PV Modules are PV topologies, working up to 350W, which embody an electronic DC to AC converter. This inverter is directly connected to the low voltage (220V) urban grid. More specifically, a high frequency Full Bridge Converter with 50Hz transformer and a current source flyback converter with two identical secondary windings are the issues of this work. Criterions for this comparison are the efficiency, the power factor, the power density and the convenience at the implementation of M.P.P.T. and anti-islanding control. Experimental results accomplished on laboratory prototypes are also presented.

This is achieved through the study, design, implementation and presentation of some initial results, of an OFDM (Orthogonal Frequency Division Multiplexing) transceiver. The design and implementation is done using the TMS320C6713 DSK development kit from "Texas Instruments Inc", in conjunction with Matlab-Simulink from "Mathworks Inc.". This procedure can easily be adopted for the development of several other systems at the domain of communications and signal processing.
