Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138400
Kind Code:
A1
Abstract:
Provided is a power conversion device capable of easily suppressing DC components on the transformer side. The power conversion device 1 is provided between a DC circuit and an AC circuit 9, said DC circuit having a positive-side DC line 8P and a negative-side DC line 8N. A positive-side arm 4Pu and a negative-side arm 4Nu are provided that are connected in series between the positive-side DC line 8P and the negative-side DC line 8N, and an AC electric path, such as an AC terminal 11, is extended from a connection point between the positive-side arm 4Pu and the negative-side arm 4Nu. An AC current sensor 6ac is provided on the AC electric path to detect the current flowing through the AC electric path. A management unit 7 is also provided to control unit converters 4 on the basis of the measured value of the AC current sensor 6ac so as to suppress the DC components of the AC electric path.
