© 2016 IEEE. This paper presents the direct and easy way to implement digitally an optimal Venturini modulation scheme for a 7.5 KVA, four-wires, matrix converter with balanced and unbalanced loads. In order to meet tight harmonic specification a single-stage LC input filter with a resistor connected in parallel with the inductor has been designed and at the output another single-stage LC filter is used. This enables stable output power and frequency over a wide range and at different load conditions. Experimental results obtained by using a DSP-FPGA system verify the effectiveness of the Venturini modulation scheme.
