A d.c./a.c. converter synthesizes an alternating voltage by suitably and at the correct instants selectively combining a plurality of direct voltage sources into a variety of series connections by means of a plurality of semiconductor controlled switches and diodes. Polarity inversion is effected with a bridge circuit comprising switches. The converter load is connected to said bridge circuit. In this way it is possible to directly generate a 220 V, 50 Hz AC voltage without inductive elements, from solar panels, using accumulator batteries. |
