POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047395
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power conversion device including a power conversion device case suitable for placement within a solar power generation site. Furthermore, the present invention aims to provide a structure for the power conversion device case that can be more compact and is designed for cooling because same is used in natural environmental conditions. A power conversion device having a power conversion unit comprising a single-phase inverter on a secondary side of a high-frequency resonant converter having DC input, said power conversion device characterized by: the output for the single-phase inverter for a plurality of power conversion units being connected in series and constituting a power conversion unit group; each phase for a three-phase alternating current being formed by using three sets of the power conversion unit groups housed inside the power conversion device case; the plurality of power conversion units constituting the power conversion unit group being arranged along the longitudinal direction of the power conversion device case; the three sets of power conversion unit groups being arranged on an upper level, middle level, and lower level, respectively, in the height direction of the power conversion device case; one end side of the power conversion device case in the longitudinal direction being an output terminal for the three sets of power conversion unit groups; the terminals of the three sets of power conversion unit groups having a common connection on the other end side of the power conversion device case in the longitudinal direction; an indoor unit for an air conditioner being arranged on at least either the right or left, in the longitudinal direction, inside the power conversion device case; an outdoor unit for an air conditioner being arranged on at least either the right or left, in the longitudinal direction, outside the power conversion device case; and the interior of the power conversion device case being cooled by cool air from the indoor unit of the air conditioner.
