Frequency converter arrangement for use in e.g. machine tool, has single-piece wire-typed printed circuit board, on which frequency converter units are parallely connected, where converter units are arranged in matrix form on board

摘要

The arrangement has a single-piece wired-type rectangular printed circuit board (1), on which frequency converter units are parallely connected. A predetermined breaking point is arranged between the converter units, so that the converter units remain parallely connected in the printed circuit board during break in the breaking point by input and output lines (2, 3). The converter units are arranged in a matrix form on the printed circuit board and connected in the printed circuit board in four orthogonal directions by the lines. The converter units are designed for a multi-phase system. An independent claim is also included for a machine tool or motor with a frequency converter.
