Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059169
Kind Code:
A1
Abstract:
A power conversion device (200) comprises first through mth control devices (Cc1 – Ccm) formed so as to be able to communicate with each other. The kth control device (Cck) transmits, to the control devices among the first through mth control devices (Cc1 – Ccm) other than the kth control device (Cck), specification information including the voltage values of a plurality of unit converters included in the kth cell set (Suk, Svk, Swk) of each of a first through third arm (A1–A3). The kth control device (Cck) receives, from each of the control devices among the first through mth control devices (Cc1 – Ccm) other than the kth control device (Cck), the specification information including the voltage values of the plurality of unit converters included in the cell set controlled by the control device. The kth control device (Cck) calculates, for each of the first through third arms (A1-A3), a representative phase value for the voltage values of the plurality of unit converters included in each arm.
