Document Type and Number:
WIPO Patent Application WO/2024/095703
Kind Code:
A1
Abstract:
A power conversion device (10) comprises first upper and lower arm switches (S1H, S1L), second upper and lower arm switches (S2H, S2L), third upper and lower arm switches (S3H, S3L), an upper arm rectification unit (S4H, D4H) and a lower arm rectification unit (S4L, D4L), first through third inductors (31–33), a connection pathway (44), a single-phase charging switch (45) that is provided to the connection pathway, first through third capacitors (161–163), a connection switch (151), and a control unit (70). The control unit performs switching control of the first upper and lower arm switches to perform a power conversion between first and fourth alternating-current terminals (Tac1, Tac4) and high- and low-potential-side direct-current terminals (TdcH, TdcL) when it has been determined that a single-phase alternating-current power supply (22) is connected to the first and fourth alternating-current terminals and the single-phase charging switch is on but the connection switch is off.
