Document Type and Number:
Japanese Patent JP2019017141
Kind Code:
A
Abstract:
To provide a power supply system capable of fixing a supply voltage to a load and fixing a corresponding voltage of a power conversion device.SOLUTION: A power supply system comprises a first switch 60 capable of switching between a first connection state in which power of 200 V generated by a solar panel 21 can be supplied to a commercial power system 40 and a second connection state in which power of 100 V can be sent out. The power supply system also comprises a transformer 70 by which the power of 100 V supplied via the first switch 60 is boosted to 200 V and outputted in the case of power failure and during power generation of the solar panel 21. The power supply system further comprises a power conditioner 32 to which the power of 200 V outputted from the transformer 70 is supplied in the case of power failure and during the power generation of the solar panel 21 and which is capable of supplying converted power of 200 V of a storage battery 31 to a load 50 in the case of power failure and during no power generation of the solar panel 21.SELECTED DRAWING: Figure 2
