POWER CONVERSION DEVICE

A power converter (10a) performs DC power conversion between a pair of first DC terminals (20) and a pair of second DC terminals (30). DC nodes of n DC/AC converters (100) are connected in parallel or in series between the first DC terminals (20). A multiple transformer (300a) has n primary windings...

Zusammenfassung:	A power converter (10a) performs DC power conversion between a pair of first DC terminals (20) and a pair of second DC terminals (30). DC nodes of n DC/AC converters (100) are connected in parallel or in series between the first DC terminals (20). A multiple transformer (300a) has n primary windings (301) and n secondary windings (302). An AC node of each DC/AC converter (100) is connected to its corresponding primary winding (301). An AC node of each AC/DC converter (200) is connected to its corresponding secondary winding (302). DC nodes of n AC/DC converters (200) are connected in series or in parallel between the second DC terminals (30). The multiple transformer (300a) is configured such that a magnetic path is shared among the n primary windings (301) and a magnetic path is shared among the n secondary windings (302).
