Document Type and Number:
WIPO Patent Application WO/2016/121632
Kind Code:
A1
Abstract:
While a path between a DC power supply (1) and a smoothing capacitor (2) is in a shut-off state in regenerative control of an inverter circuit (30), a control circuit (40) of a power conversion device (100) carries out control by switching, at predetermined switching intervals, between first control for turning on upper switching elements (31U, 31V, 31W) in the inverter circuit (30) and turning off all lower switching elements (32U, 32V, 32W) and second control for turning on the lower switching elements (32U, 32V, 32W) and turning off all the upper switching elements (31U, 31V, 31W).
