Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216158
Kind Code:
A1
Abstract:
Provided is a power conversion device provided with a power supply main circuit unit (2) and a power supply control unit (3). The power supply main circuit unit (2) has a switching element (11) and a reactor (12) and performs power conversion on an input voltage having an AC voltage component superimposed on a DC voltage component to output the converted input voltage to a load. The power supply control unit (3) determines the turn-on timing of the switching element (11) so as to delay the turn-on timing of the switching element (11) when the sensed value (Vinsen) of the input voltage becomes large due to the AC voltage component superimposed on the DC voltage component as compared to when the sensed value (Vinsen) of the input voltage becomes small due to the AC voltage component superimposed on the DC voltage component.
