Abstract
The disclosure reduces the occurrence of an inrush current upon electrical connection of a storage cell, allowing immediate use. A power supply apparatus is configured to convert DC power from a solar cell and a storage cell into AC power and includes: a first capacitor disposed between the solar cell and the storage cell; and a controller configured to charge the first capacitor with power from the solar cell or a power grid and, after a first voltage of the first capacitor exceeds a second voltage of the storage cell, to electrically connect the storage cell with the first capacitor.
Claims8
A power supply apparatus,
- configured to convert DC power from a solar cell and a storage cell into AC power, and
- comprising:
- a first capacitor disposed between the solar cell and the storage cell;
- and
- a controller configured to charge the first capacitor with the power from the solar cell or a power grid and, after a first voltage of the first capacitor exceeds a second voltage of the storage cell, to electrically connect the storage cell with the first capacitor.
A power supply system comprising:
- a power supply apparatus configured to convert DC power from a solar cell and a storage cell into AC power, a storage cell, and a solar cell,
- wherein the power supply apparatus includes a first capacitor disposed between the solar cell and the storage cell, and a controller configured to charge the first capacitor with the power from the solar cell or a power grid and, after a first voltage of the first capacitor exceeds a second voltage of the storage cell, to electrically connect the storage cell with the first capacitor.
A control method of a power supply apparatus comprising:
- charging a first capacitor with a power from a solar cell or a power grid;
- and
- electrically connecting, after a first voltage of the first capacitor exceeds a second voltage of a storage cell, the storage cell with the first capacitor.
