Title:
電力変換装置
Document Type and Number:
Japanese Patent JP7146115
Kind Code:
B2
Abstract:
This power conversion device has a plurality of single-phase inverters (2I, 3I), at least one of which is connected to an external power supply (10S), wherein the voltage ratios between the DC power supply voltages of the respective single-phase inverters (2I, 3I) are constant, and is provided with: a comparison unit (22) for calculating comparison standard values by dividing the voltage ratios by the ratios between the detected voltage values of the DC power supply voltages of the single-phase inverters (2I, 3I) and the target values of the respective DC power supply voltages and performing comparison processing on the comparison standard values; and an output pattern determination unit (23) for determining, on the basis of the comparison results obtained by the comparison unit (22) and a predetermined selection condition, an output pattern that is a combination of the single-phase inverters (2I, 3I) from which voltages are to be output. The comparison unit (22) compares an average value of at least some of the plurality of comparison standard values with the respective comparison standard values.
