Title:
POWER CONVERSION DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/068815
Kind Code:
A1
Abstract:
This power conversion device, for performing power conversion between multiple DC power sources and an AC system through an intermediate bus, is provided with multiple DC/DC converters disposed between the intermediate bus and the multiple DC power sources, and intermediate capacitor which is connected to the intermediate bus, a DC/AC converter disposed between the intermediate bus and the AC system, and a control unit which controls the multiple DC/DC converters and the DC/AC converter, wherein the control unit exercises control such that the active power outputted by the DC/AC converter is distributed to the multiple DC/DC converters, and such that the total value of the reactive power outputted by the DC/AC converter and the intermediate capacitor is distributed to the multiple DC/DC converters with a distribution coefficient different from the distribution coefficient of the active power.
