Abstract
Disclosed are a power supply device for air mobility and a method thereof. The power supply device includes a plurality of power supply lines that distribute power of a fuel cell stack in parallel, one-to-one matches the plurality of power supply lines with a plurality of rotor structures. The power supply device supplies power to one rotor structure through one power supply line, thereby supplying power to the remaining rotor structures through the remaining power supply lines even when a short circuit occurs in a semiconductor switching element on any one of the plurality of power supply lines.
Claims18
A power supply device comprising:
- a fuel cell stack configured to supply power to an air mobility;
- and
- a converter including a plurality of power supply lines that distribute power of the fuel cell stack in parallel and are configured to one-to-one match the plurality of power supply lines with a plurality of rotor structures and supply power to one rotor structure through one power supply line;
- wherein the converter includes:
- a first power supply line configured to distribute the power of the fuel cell stack in parallel and supply the power to a first rotor structure;
- a second power supply line configured to distribute the power of the fuel cell stack in parallel and supply the power to a second rotor structure;
- and
- a third power supply line configured to distribute the power of the fuel cell stack in parallel and supply the power to a third rotor structure.
A method for supplying power comprising:
- one-to-one matching, by a converter, a plurality of power supply lines which distributes power of a fuel cell stack in parallel with a plurality of rotor structures;
- and
- supplying, by the converter, power to one rotor structure through one power supply line;
- wherein the supplying of the power to the rotor structure includes:
- distributing, by a first power supply line, the power of the fuel cell stack in parallel to supply the power to a first rotor structure;
- distributing, by a second power supply line, the power of the fuel cell stack in parallel to supply the power to a second rotor structure;
- and
- distributing, by a third power supply line, the power of the fuel cell stack in parallel to supply the power to a third rotor structure.
