Document Type and Number:
WIPO Patent Application WO/2017/115621
Kind Code:
A1
Abstract:
The present invention performs booster circuit switching and switches between a full-wave rectifier circuit and a voltage-doubler rectifier circuit in order to improve a power factor. This power conversion device (100) comprises: a single-phase full bridge rectifier circuit (1); a reactor (7) that is connected with a power source (9) in series between the power source (9) and one of the input ports (15, 16) of the single-phase full bridge rectifier circuit (1); capacitors (21, 22) that are connected, over a connection point (23), to one another in series between output ports (17, 18) of the single-phase full bridge rectifier circuit (1); a first switch (51) that is connected between an input port (16) and the connection point (23); and a second switch (52) that is connected between the input ports (15, 16).
