Title:
Power converter
Document Type and Number:
Japanese Patent JP6188827
Kind Code:
B2
Abstract:
In a power conversion system in which one or more converter cells (10) are connected in series to form an arm (5, 6) for each phase, a control device (20) includes a voltage command generating unit (21) for generating a positive arm voltage command Vp + and a negative arm voltage command Vp- for each phase. The voltage command generating unit (21) includes an AC current control unit (23), a circulating current control unit (24), and a command distributing unit (25). On the basis of input voltage commands, the command distributing unit (25) subtracts voltage drop portions due to inductance values in the arms (5, 6) from respective voltages assigned as outputs of the positive arm (5) and the negative arm (6), to distribute voltage components, thereby determining the positive arm voltage command Vp + and the negative arm voltage command Vp - .
