Embodiment Construction

[0057] Specifically, in figure 1 A converter 10 is shown in , wherein the converter 10 is designed as a multi-stage converter. The converter 10 has three AC voltage terminals L1, L2, L3 for connection to a three-phase AC grid. Furthermore, the converter 10 comprises DC voltage terminals 104 , 105 , 106 , 107 , 108 and 109 for connection to the positive terminal 102 and the negative terminal 103 .

[0058] Positive terminal 102 and negative terminal 103 can be connected to the figure 1 Positive and negative poles of the DC grid not shown.

[0059] The AC voltage terminals L1, L2, L3 are respectively connectable to the secondary winding of the transformer. The primary winding of the transformer is connected to the figure 1 AC grid not shown. Within the scope of the invention, a direct electrical connection to the AC mains is also possible, for example via an intermediate circuit with coils or choke coils or capacitive components.

[0060] The power semiconductor valve 1...
