Abstract
There is provided a power supply system including a first power supply and a second power supply. The power supply system includes a power conversion circuit capable of bidirectionally sending and receiving power by bidirectional voltage conversion between the first power supply and the second power supply, converting the first voltage from the first power supply to output a third voltage and a fourth voltage, and converting the second voltage from the second power supply to output the third voltage and the fourth voltage.
Claims18
A power supply system comprising a power conversion circuit, the power conversion circuit being configured to:
- bidirectionally send and receive power by bidirectional voltage conversion between a first power supply and a second power supply, the first power supply outputting a first voltage and the second power supply outputting a second voltage different from the first voltage;
- convert the first voltage output from the first power supply to output a third voltage different from the first voltage and the second voltage and to output a fourth voltage different from the first voltage, the second voltage, and the third voltage;
- and
- convert the second voltage output from the second power supply to output the third voltage and the fourth voltage,
- wherein the first power supply comprises a first sub-power supply and a second sub-power supply,
- wherein the power conversion circuit comprises:
- a first sub-power conversion circuit configured to perform bidirectional voltage conversion between the first sub-power supply and the second power supply to convert a voltage output from the first sub-power supply to output the third voltage to the second power supply;
- and
- a second sub-power conversion circuit configured to perform bidirectional voltage conversion between the second sub-power supply and the second power supply to convert a voltage output from the second sub-power supply to output the fourth voltage to the second power supply, and
- wherein the first sub-power conversion circuit and the second sub-power conversion circuit are configured to bidirectionally send and receive power between the first sub-power supply.
