Abstract

A connection structure of a plurality of switching modules that reduces required insulation voltage significantly when the plurality of switching modules is connected to each other in series is proposed. A switching module connection structure includes: n (n≥1, integer) switching modules arranged in two or more columns and all connecting to each other in series from a first switching module in a first column to a last switching module in a last column; and insulating members disposed between at least some switching modules for each column.

First claim

The invention claimed is:

1. A switching module connection structure comprising:
n (n≥1, integer) switching modules arranged in two or more columns and all connecting to each other in series from a first switching module in a first column to a last switching module in a last column; and
insulating members disposed between at least two switching modules for each column,
wherein the n switching modules are grouped by a plurality of switching module groups composed of m (m<n, integer) switching modules for each column, and each of the insulating members is inserted between the switching module groups, and
wherein the m switching modules in each switching module group are directly connected to each other in series, and an uppermost switching module of the m switching modules is serially connected to a lowermost switching module in any one switching module group of an adjacent column.

2. The switching module connection structure of claim 1 , wherein the switching modules in the two or more columns are arranged in parallel to each other.

3. The switching module connection structure of claim 1 , wherein,
in the switching modules arranged in the two or more columns, the uppermost switching module of a k-th switching module group in each of the switching module groups of the first column is serially connected to the lowermost switching module of a k-th switching module group of an adjacent second column, and
the lowermost switching module of the k-th switching module group in each of the switching module groups of the first column is serially connected to the uppermost switching module of a (k+1)-th switching module group of the second column.

4. The switching module connection structure of claim 1 , wherein,
in the switching modules arranged in the two or more columns, the uppermost switching module of a k-th switching module group in each of the switching module groups of the first column is serially connected to the lowermost switching module of a (k−1)-th switching module group of a second column adjacent to a left side of the first column, and
the lowermost switching module of the k-th switching module group in each of the switching module groups of the first column is serially connected to the uppermost switching module of a (k+1)-th switching module group of a third column adjacent to a right side of the first column.

5. The switching module connection structure of claim 1 , wherein the first switching module of the first column and the last switching module of the last column are respectively connected to a DC line.

6. The switching module connection structure of claim 1 , further comprising:
a rack structure provided with a first space for mounting the switching modules in order to stack the switching modules arranged in the two or more columns and a second space for mounting the insulating members,
wherein the switching modules and the insulating members are respectively mounted in the first space and the second space of the rack structure in a state of being vertically stacked.
