Abstract
A converter circuit arrangement is disclosed for matching a variable DC voltage to a drive circuit for producing drive signals and having a three-point DC voltage intermediate circuit (2), which three-point DC voltage intermediate circuit (2) is formed by a first capacitor (3) and a second capacitor (4) connected in series with it, with one connection of the first capacitor (3) forming an upper connection (5) of the three-point DC voltage intermediate circuit (2), and the first capacitor (3) forming a center point connection (6) at the junction point with the second capacitor (4) and one connection of the second capacitor (4) forming a lower connection (7) of the three-point DC voltage intermediate circuit (2). A first partial converter system (8) and a second partial converter system (9) are provided, with the input side of the first partial converter system (8) being connected to a first pole (10) of a DC voltage source (11) which produces the DC voltage, and the input side of the second partial converter system (9) being connected to a second pole (12) of the DC voltage source (11), a first output (13) of the first partial converter system (8) being connected to the upper connec…
