Title:
MATRIX CONVERTER
Document Type and Number:
WIPO Patent Application WO/2013/080744
Kind Code:
A1
Abstract:
A matrix converter according to an embodiment is equipped with: a power conversion unit which has multiple bi-directional switches; a control unit for controlling the power conversion unit; and a current detection unit for detecting a current which flows on the output side of the power conversion unit. The control unit extracts a high-frequency component which is contained in the current detected by the current detection unit, adjusts an output current command on the basis of this high-frequency component, and controls the power conversion unit on the basis of the adjusted output current command.
