<P>PROBLEM TO BE SOLVED: To utilize the output capacity of a generator to its maximum and to greatly curtail its part items, in a power unit from which a single-phase three-line system output can be taken out. <P>SOLUTION: The output of a generator 1 is rectified by a DC converter 2, and given to a DC-DC converter 3. The DC-DC converter 3 is composed of first and second DC-DC converters 3-1 to 3-2. A voltage stepped up by the first DC-DC converter 3-1 is given as an input voltage to an inverter of the DC-AC converter 4. A voltage stepped down by the second DC-DC converter 3-2 forms its neutral point. The single-phase three-phase system output with its neutral point formed by the output of the second DC-DC converter 3-2 is led out of the DC-AC converter 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
