Provision of a low-inductive rail for three-point phase module
First Claim
1. A low-inductive busbar arrangement having three planes, comprising:
- a three-point phase module of a polyphase three-point power converter having switches and at least two neutral point diodes, and further including;
at least one turn-off semiconductor switch for each switch of the three-point phase module, at least one diode being provided for each of the neutral point diodes, and terminal, branch and connection busbars distributed between the planes, wherein the planes are mutually electrically insulated from one another via insulation layers, and wherein the planes are arranged parallel to one another.

Abstract
A low-inductive busbar arrangement for a three-point phase module of a polyphase three-point power converter is provided. At least one turn-off semiconductor switched being provided for each switch of this three-point phase module and at least one diode being provided for each of the two neutral point diodes. Connection busbars of this three-point-phase module are distributed between three busbar planes of the low-inductive busbar arrangement, which are mutually electrically insulated from one another in each case with insulation layer and are arranged in a plan-parallel manner. A low-inductive busbar arrangement for a three-point phase module is thus obtained which has three busbar planes, irrespective of the series connection number.
