`AMENDMENTS TO THE CLAIMS
`
`This listing of claims will replace all prior versions, and listings, of claims in the application:
`
`Listing of Claims
`
`1. (Currently amended) A power supply device comprising:
`
`a first unidirectional converter that converts power to be supplied from an input power
`
`supply to a first converted power by switching, and supplies the first converted power to a power
`
`storage device in a single direction;
`
`a second unidirectional converter that converts, by switching, the first converted power to
`
`be supplied from the first unidirectional converter or power to be supplied from the power
`
`storage device to a second converted power, and supplies the second converted power to a load
`
`device in a single direction,
`
`a noise filter that reduces noise generated in the first unidirectional converter and the
`
`second unidirectional converter, and
`
`a shield that covers the first unidirectional converter, the second unidirectional converter
`
`7
`
`and the noise filter, and blocks electromagnetic noise,
`
`
`
`and—wherein a branch point at which a power line from the first unidirectional converter to the
`
`power storage device intersects a power line from the second unidirectional converter to the
`
`power storage device is nearer—closer to the first unidirectional converter than to the power
`
`storage device, wherein the noise filter is provided between the first unidirectional converter and
`
`the power storage device, and between the power storage device and the second unidirectional
`
`converter, wherein a first terminal of the noise filter is directly coupled to the branch point, and a
`
`second terminal of the noise filter is coupled to the power storage device;
`
`wherein the power supply device is configured to operate in:
`
`a first state in which the first unidirectional converter supplies the first converted power
`
`to the power storage device and the second unidirectional converter does not eper—ateconvert
`
`supply power,

`Reply to Office Action dated March 8, 2019
`
`a second state in which the first unidirectional converter does not operate-convert supply
`
`wand the second unidirectional converter converts the power to be supplied from the power
`
`storage device to the load; and
`
`a third state in which the first unidirectional converter converts the power to be supplied
`
`from the input power supply and the second unidirectional converter converts the first converted
`
`power to be supplied from the first unidirectional converter to the load.
`
`2. (Previously presented) The power supply device of Claim 1,
`
`wherein the noise filter is interposed on a current path between the first unidirectional
`
`converter and the power storage device, and the noise filter is not interposed on a current path
`
`between the first unidirectional converter and the second unidirectional converter.
`
`3. (Previously presented) The power supply device of Claim 1,
`
`wherein a current capacity of the noise filter is higher than any of a first maximum value
`
`of a current that flows from the first unidirectional converter and a second maximum value of a
`
`current that flows to the second unidirectional converter, and is lower than the total value of the
`
`first maximum value and the second maximum value.
`
`4. (Original) The power supply device of Claim 1, wherein the noise filter has a common mode
`
`choke coil.
`
`5. (Cancelled)
`
`6. (Cancelled)
`
`7. (Cancelled)
`
`8. (Cancelled)
`
`9. (Previously presented) The power supply device of Claim 1,

`
`
`Appln. No. 15/316,687
`Amendment dated June 10, 2019
`Reply to Office Action dated March 8, 2019
`
`wherein the power supply device is mounted to a vehicle,
`
`the input power supply is an AC power supply outside the vehicle,
`
`the first unidirectional converter is configured of an AC-DC converter and a DC-DC
`
`converter, and
`
`the second unidirectional converter is configured of a DC-DC converter.
`
`10. (Previously presented) The power supply device of Claim 1, further comprising:
`
`a first line filter coupled between the input power supply and the first unidirectional
`
`converter, and
`
`a second line filter coupled between the second unidirectional converter and the load
`
`device,
`
`wherein the shield covers the first line filter and the second line filter.
`
`11. (New) The power supply device of claim 1, wherein the power supply device is
`
`mounted to a vehicle which mounts an electrical component that does not belong to the power supply
`
`device.
`
`12. (New) The power supply device of claim 11, wherein the shield does not cover the power
`
`storage device and the electrical component.
