Title:
POWER CONVERSION DEVICE AND DEVICE FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2012/176327
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power conversion device having the reduced numbers of reactors and IGBTs and being capable of obtaining variable amplitude and variable frequency power with a simple configuration and to provide a device for controlling the power conversion device.
In the present invention, in order to accomplish the above purpose, a reactor, a first cluster that is a series body consisting of a plurality of unit cells, and a second cluster that is another series body consisting of a plurality of unit cells are connected in series to constitute a leg, and three sets of the leg are delta-connected. The three connection points of the delta-connected legs are connected to the respective three phases of first three-phase AC equipment. The connection point between the first and second clusters of each leg is connected to each of the phases of second three-phase AC equipment.
