Abstract
A power conversion device connected in parallel to a second power conversion device including power conversion circuitry that performs power conversion by changing a connection state between first multiple lines on a primary side and second multiple lines on a secondary side, baseline selection circuitry that selects one of the second multiple lines on the secondary side as a baseline and partial modulation control circuitry that controls the power conversion circuitry to maintain a state in which the baseline is connected to one of the first multiple lines on the primary side and to change a connection state between other second multiple lines on the secondary side and the first multiple lines on the primary side, wherein the baseline selection circuitry switches a line selected as the baseline based on a switching timing used by second baseline selection circuitry of the second power conversion device to select a second baseline.
