The performance of the three phase AC/DC Flyback and Cuk converters are verified at 220 Vrms phase voltage, 8400W and 750 W output power respectively through MATLAB/simulation model and a good consistency is achieved. The main design objective is to produce the lowest cost within a small-size system The study includes the use of optimum number of cells to be interleaved and the associated phase shifts among the cells are determined on the design of a isolated flyback transformer with the lowest leakage inductance and selection of components providing the lowest parasistic effects critical for obtaining high efficiency and good performance. The primary market target of the converter is within the telecommunications industry where it supplies high-quality dc power to the telecom loads and performs high-capacity battery charging while providing zero harmonic emission and unity power factor to the utility grid. Comparisons of three phase converters is done to identify the converters with low cost/high efficiency for the system by reducing number of stages and improve quality in terms of power factor correction, reduced THD at input ac mains and regulated dc output.
