<P>PROBLEM TO BE SOLVED: To provide a converter circuit protected from a short-circuit current. <P>SOLUTION: The converter circuit has a DC voltage circuit (1) formed of a DC voltage circuit subsystem (2.1) having a first energy storage (3), a second energy storage (4) connected to the first energy storage (3) in series, and a fuse (5). At least a pair of branch lines (6) having a power semiconductor switch is provided in each phase (P, S, T), and connected to the DC voltage circuit (1) in parallel. The fuse (5) establishes connection between the first energy storage (3) and the second energy storage (4) in order to achieve the low inductance converter circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
