<p>A converter circuit has a DC voltage circuit (1) formed by two series-connected capacitors and a first (5) current rise limiting network (5) connected to a first main terminal (2) and a second current rise limiting network (10) with an inductance (11) and a resistance (12) connected to the second main terminal (3). A first voltage limiting network (15) is connected in parallel to a series circuit of the first and second power semiconductor switches (S1,S2) and to a diode of the first current limiting network (5). A second voltage limiting network (16) is connected in parallel to the series circuit of the third and fourth power semiconductor switches (S3,S4) and to the diode (14) of the second current limiting network (10).</p> |
