Abstract
A converter system for increasing a DC voltage is specified, which converter system is formed by at least one converter system element (2) having an input-side DC circuit (3) connected to a first voltage inverter (5), and by a center point connection (4), which is formed by at least two series-connected DC capacitances (21a; 21b). The center point connection (4) is connected to a first connection (22a) of the primary winding (8) of a transformer (7), with the output of the first voltage inverter (5) being connected to a second connection (22b) of the primary winding (8) of the transformer (7), and the secondary winding (9) of the transformer (7) being connected to the input of an output-side converter (6) which is provided for producing an output-side DC voltage. Furthermore, the first voltage inverter (5) is connected by means of a first and a second input connection (23a; 23b) to the DC intermediate circuit (3), and the center point connection (4) is connected via a third input connection (23c) of the first voltage inverter (5) to a center point voltage stage (24) of the first voltage inverter (5), which is in the form of a stepping circuit. Furthermore, a wind power system havin…
