Abstract
A DC power distribution system includes a DC bus that distributes DC power, a first power converter, and a voltage stabilizer. The first power converter is connected between the DC bus and a load, and converts DC power from the DC bus into electric power required by the load. The voltage stabilizer is connected to the DC bus in parallel with the first power converter. The voltage stabilizer supplies electric power to the DC bus, the electric power corresponding to fluctuation of an input voltage input from the DC bus to the first power converter and corresponding to DC power supplied from the DC bus to the first power converter.

A direct current (DC) power distribution system comprising:
- a DC bus that distributes DC power;
- a first power converter that converts DC power from the DC bus into electric power required by a load, the first power converter being connected between the DC bus and the load;
- and
- a voltage stabilizer connected to the DC bus in parallel with the first power converter, wherein
- the voltage stabilizer supplies electric power to the DC bus, the electric power supplied from the voltage stabilizer corresponding to fluctuation of an input voltage input from the DC bus to the first power converter and corresponding to DC power supplied from the DC bus to the first power converter,
- wherein
- the voltage stabilizer:
- varies DC power supplied from the DC bus to the first power converter and the voltage stabilizer, in accordance with fluctuation of the input voltage, and
- operates to compensate for a deviation between a first DC power and a second DC power, the first DC power being supplied to the first power converter and the voltage stabilizer, the second DC power being supplied to the first power converter.
A voltage stabilizer of a DC power distribution system, wherein
- the DC power distribution system includes:
- a DC bus;
- and
- a first power converter that converts DC power from the DC bus into electric power required by a load, the first power converter being connected between the DC bus and the load, and
- the voltage stabilizer supplies electric power to the DC bus, the electric power supplied by the voltage stabilizer corresponding to fluctuation of an input voltage input from the DC bus to the first power converter and corresponding to DC power supplied from the DC bus to the first power converter,
- wherein
- the voltage stabilizer:
- varies DC power supplied from the DC bus to the first power converter and the voltage stabilizer, in accordance with fluctuation of the input voltage, and
- operates to compensate for a deviation between a first DC power and a second DC power, the first DC power being supplied to the first power converter and the voltage stabilizer, the second DC power being supplied to the first power converter.
