Title:
POWER CONVERSION DEVICE AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138130
Kind Code:
A1
Abstract:
A power conversion device of the present invention is provided with: a boost converter unit having a reactor to which a direct current voltage is inputted, a switching element connected to the reactor in parallel, and a backflow prevention element connected to the reactor in series; a smoothing capacitor that smoothes an output voltage of the boost converter unit; an inverter unit that converts an output voltage into an alternating current voltage, said output voltage having been smoothed by the smoothing capacitor; a dew condensation state detection unit that detects the state of dew condensation generated due to a cooler that cools the boost converter unit and the inverter unit; and a control unit that controls operations of the boost converter unit. The control unit has: a determining means that determines the state of the dew condensation detected by means of the dew condensation state detection unit; and a boost control means that controls boost operations of the boost converter unit on the basis of determining results obtained from the determining means.
