Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a diagram showing a vehicle 1 to which a power supply device 100 according to an embodiment of the present invention is applied.
As shown in fig. 1, the power supply device 100 is a charging device for charging a battery 2 mounted on a vehicle 1, for example, and operates by supplying electric power from an external ac power supply. The power supply apparatus 100 is configured to be connectable to a single-phase power supply and a three-phase power supply 10 as external power supplies.
Fig. 1 shows an example in which a three-phase power supply 10 is connected to a power supply device 100, and the three-phase power supply 10 includes a first power supply 10A, a second power supply 10B, and a third power supply 10C that are Y-connected around a neutral point N1 connected to a ground line G. The respective ground ends of the first power supply 10A, the second power supply 10B, and the third power supply 10C are connected to a neutral point N1. The ground line G is a line corresponding to ground.
The power supply device 100 includes a first terminal 101A, a second terminal 101B, a third terminal 101C, a fourth terminal 102, processing circuits 103A, 103B, and 103C, a noise filter 104, and the like.
The first terminal 101A is connected to the first power supply end portion L1 of the first power supply 10A in the three-phase power supply 10. The first terminal 101A is connected to a first power line a1 in the power supply device 100 via a noise filter 104. As shown in fig. 2, when the single-phase power supply 20 is connected to the power supply apparatus 100, the first terminal 101A is connected to the power supply end portion L of the single-phase power supply 20.
As shown in fig. 1, the second terminal 101B is connected to the second power supply end portion L2 of the second power supply 10B of the three-phase power supply 10. The second terminal 101B is connected to a second power line B1 in the power supply apparatus 100 via a noise filter 104.
The third terminal 101C is connected to the third power supply end portion L3 of the third power supply 10C of the three-phase power supply 10. The third terminal 101C is connected to a third power line C1 in the power supply device 100 via a noise filter 104.
The fourth terminal 102 is connected to a ground line G, which is a neutral point N1 of the three-phase power supply 10 corresponding to the ground end of the three-phase power supply 10. The fourth terminal 102 is connected to the neutral line D in the power supply device 100 via a noise filter 104. In addition, a neutral line D is connected to each of the first neutral line a2, the second neutral line B2, and the third neutral line C2.
The processing circuits 103A, 103B, and 103C are circuits for converting electric power supplied from the three-phase power supply 10 or the single-phase power supply into electric power for charging the battery 2, and include a power factor correction circuit, a DC/DC conversion circuit, and the like.
When the single-phase power supply 20 is connected to the power supply apparatus 100, power is supplied from the single-phase power supply 20 to the processing circuits 103A and 103B (see fig. 2).
The noise filter 104 is a three-phase four-wire common mode choke coil (magnetic member) for removing common mode noise in the power supply device 100. The noise filter 104 is provided at a stage preceding the processing circuits 103A, 103B, and 103C. The noise filter 104 has a first winding 104A, a second winding 104B, a third winding 104C, a fourth winding 104D, and a magnet core 104E.
The first winding 104A is disposed between the first terminal 101A and the first power line a 1. The second winding wire 104B is disposed between the second terminal 101B and the second power line B1. The third winding wire 104C is disposed between the third terminal 101C and the third power line C1.
The fourth winding 104D is disposed between the fourth terminal 102 and the neutral line D. The resistance of the fourth winding 104D is smaller than the resistances of the first, second, and third windings 104A, 104B, and 104C.
Specifically, the fourth winding 104D is thicker than the first, second, and third windings 104A, 104B, and 104C. Thus, more electric power (current) can be supplied to the fourth winding 104D than to the first, second, and third windings 104A, 104B, and 104C. In this embodiment, the resistance of the fourth wire 104D may be smaller than the resistance of the second wire 104B, and the resistance of the fourth wire 104D is not necessarily smaller than the resistances of the first wire 104A, the second wire 104B, and the third wire 104C.
The magnet core 104E is formed in a circular shape. The first winding 104A, the second winding 104B, the third winding 104C, and the fourth winding 104D are wound around different portions of the magnet core 104E.
In the noise filter 104 configured as described above, when a current flows through each winding, a magnetic flux is generated at each winding portion of the magnetic core 104E. By these magnetic fluxes strengthening each other, the noise filter 104 obtains a large impedance when common mode noise is generated, thereby suppressing the common mode noise.
The switching unit 105 is, for example, a relay, and switches the connection state of the power line between a first state when the three-phase power supply 10 is used and a second state when the single-phase power supply is used.
The first state is a state in which power from the first power supply 10A of the three-phase power supply 10 can be supplied to the first power line a1, and power from the second power supply 10B of the three-phase power supply 10 can be supplied to the second power line B1. The second state is a state in which power from the single-phase power supply 20 can be supplied to the first power line a1 and the second power line B1.
The switching unit 105 is provided upstream of the noise filter 104 in the power supply direction (the direction from the left to the right in fig. 1 and the like) of the three-phase power supply 10 or the single-phase power supply 20. Switching unit 105 includes first fixed contact 105A, second fixed contact 105B, and movable contact 105C.
The first fixed contact 105A is provided on the fourth power line a3 connecting the first terminal 101A and the first winding 104A. The second fixed contact 105B is connected to the second terminal 101B.
When switching unit 105 is in the first state, movable contact 105C and second fixed contact 105B are connected. In this case, the first power line a1 is disconnected from the second power line B1, and the second terminal 101B is connected to the second power line B1 via the fifth power line B3 and the second winding wire 104B.
By so doing, electric power from the first power supply 10A of the three-phase power supply 10 is supplied to the first power line a1 via the first winding wire 104A, and electric power from the second power supply 10B of the three-phase power supply 10 is supplied to the second power line B1 via the second winding wire 104B.
As shown in fig. 2, when switching unit 105 is in the second state, movable contact 105C is connected to first fixed contact 105A. In this case, the first power line a1 is connected to the second power line B1 via the fifth power line B3 and the second winding 104B, and the second terminal 101B is disconnected from the second power line B1.
By so doing, the electric power from the single-phase power supply 20 is supplied to the first power line a1 and the second power line B1 via the first winding wire 104A and the second winding wire 104B. In this case, the amount of power from the single-phase power source 20 is distributed to each of the first winding 104A and the second winding 104B and supplied to the first power line a1 and the second power line B1.
For example, when the first winding 104A and the second winding 104B have the same resistance value, half the amount of electric power of the single-phase power supply 20 is supplied to each of the first power line a1 and the second power line B1.
However, when the three-phase power supply 10 is used, the phases of the respective electric powers of the first power supply 10A, the second power supply 10B, and the third power supply 10C are shifted by 120 °, and the sum of the three-phase electric powers is 0, so the electric power amount of the neutral line D is 0.
In contrast, in the case of using the single-phase power supply 20, the amount of electric power of the neutral line D is equal to the amount of electric power supplied from the single-phase power supply 20. For example, it is assumed that the amount of power supplied from the single-phase power supply 20 is larger than the amount of power supplied from each of the power supplies 10A, 10B, and 10C of the three-phase power supply 10.
In this case, the electric power supplied from the single-phase power supply 20 passes through two power lines, i.e., the first power line a1 and the second power line B1, via the first winding wire 104A and the second winding wire 104B. Therefore, when the single-phase power supply 20 is used, the amount of electric power 2 times that of each of the power supplies 10A, 10B, and 10C of the three-phase power supply 10 can be supplied to the subsequent stage of the noise filter 104.
However, if the fourth winding 104D is made to have the same thickness as the other windings, the power corresponding to the first power line a1 and the second power line B1 may be applied to the fourth winding 104D when the single-phase power supply 20 is used, and therefore, the allowable power level of the fourth winding 104D may be exceeded.
In the present embodiment, since the resistance value of the fourth winding 104D is smaller than the resistance values of the first winding 104A, the second winding 104B, and the third winding 104C as described above, the amount of power passing through the neutral line D can be allowed when the single-phase power supply 20 is used.
As a result, the noise filter 104 corresponding to both the single-phase power supply 20 and the three-phase power supply 10 can be provided.
In the conventional three-phase four-wire type configuration, since the windings are all the same in thickness, all the windings are made relatively thick in order to cope with a single-phase power supply. Therefore, the noise filter may be large in size and high in cost.
In contrast, in the present embodiment, since only the fourth winding 104D is made thick, it is possible to achieve downsizing and cost reduction as compared with the conventional configuration.
In addition, by adopting a three-phase four-wire configuration, the total number of windings of the noise filter 104 can be 4. Therefore, as compared with a configuration in which a winding is provided for each neutral line having a neutral line corresponding to each power line, the number of windings can be reduced, and further, downsizing and cost reduction can be achieved.
In the above embodiment, the switching unit 105 is provided upstream of the noise filter 104, but the present invention is not limited to this. For example, as shown in fig. 3, the switching unit 105 may be provided downstream of the noise filter 104 in the power supply direction.
First fixed contact 105A of switching unit 105 in this case is provided on first power line a 1. The second fixed contact 105B is provided on a sixth power line B4 connected to the second winding wire 104B. Movable contact 105C is connected to second power line B1, and to either one of first fixed contact 105A and second fixed contact 105B.
When switching unit 105 is in the first state, movable contact 105C and second fixed contact 105B are connected. In this case, the first power line a1 is disconnected from the second power line B1, and the second terminal 101B is connected to the second power line B1 via the fifth power line B3, the sixth power line B4, and the second winding 104B.
By so doing, electric power from the first power supply 10A of the three-phase power supply 10 is supplied to the first power line a1 via the first winding wire 104A, and electric power from the second power supply 10B of the three-phase power supply 10 is supplied to the second power line B1 via the second winding wire 104B.
As shown in fig. 4, when switching unit 105 is in the second state, movable contact 105C is connected to first fixed contact 105A. In this case, the first power line a1 is connected to the second power line B1, and the second terminal 101B is disconnected from the second power line B1.
By so doing, the electric power from the single-phase power supply 20 is supplied to the first power line a1 and the second power line B1 via the first winding wire 104A.
That is, even with such a configuration, it is possible to achieve downsizing and cost reduction of the noise filter 104 while corresponding to both the single-phase power supply 20 and the three-phase power supply 10.
In this configuration, the noise filter 104 is directly connected to the first terminal 101A, the second terminal 101B, the third terminal 101C, and the fourth terminal 102, and therefore, is advantageous from the viewpoint of noise removal.
In this configuration, the first winding 104A is required to allow the amount of power supplied from the single-phase power supply 20, and therefore the resistance value of the first winding 104A is smaller than the resistance values of the second winding 104B and the third winding 104C. For example, the first winding 104A is thicker than the second winding 104B and the third winding 104C. Therefore, the first winding 104A is thinner than the fourth winding 104D in the structure shown in fig. 1 and 2 from the viewpoint of downsizing, and therefore, it is more advantageous than the structure shown in fig. 3 and 4. For example, if the resistance of the fourth winding 104D is smaller than the resistance of the second winding 104B, the resistance of the first winding 104A may be larger than the resistance of the second winding 104B.
In the above embodiment, the magnet core 104E is formed in a circular shape, but the present invention is not limited to this, and may be formed in an elliptical shape as shown in fig. 5, for example.
The magnet core 104E has a pair of linear portions E1 and a pair of curved portions E2.
With such a configuration, the fourth winding 104D, which is thicker than the other windings, can be provided in any one of the pair of linear portions E1. Therefore, the relatively thick winding wire can be wound while securing the space for winding the magnet core 104E, so that the winding efficiency of the fourth winding wire 104D can be improved.
In the above-described embodiment, the resistance value of the winding is adjusted by changing the thickness of the winding, but the present invention is not limited to this, and the resistance value of the winding may be adjusted by other methods such as changing the material of the winding.
For example, the fourth winding 104D may be formed of a plurality of wires. With such a configuration, the resistance value of the winding can be reduced while the winding is made relatively thin, and therefore the fourth winding can be easily wound around the magnet core.
In addition, in consideration of the characteristics of the magnetic member and the like, any one of the structure in which the thickness of the fourth winding wire 104D is changed and the structure in which the fourth winding wire 104D is formed of a plurality of wires may be appropriately selected.
In the above-described embodiment, the second state of switching unit 105 is set to a state in which the power from single-phase power supply 20 can be supplied to first power line a1 and second power line B1, but the present invention is not limited to this. For example, the second state may be a state in which power from the single-phase power supply 20 can be supplied to the first power line a1 and the third power line C1, or a state in which power from the single-phase power supply 20 can be supplied to the first power line a1, the second power line B1, and the third power line C1.
Although the switching unit 105 is provided in the configuration shown in fig. 3 and 4, the switching unit may not be provided when the processing circuit 103A corresponding to the first power line a1 can allow the amount of power of the single-phase power supply 20.
In the above-described embodiment, the configuration in which the switching unit 105 is a relay is illustrated, but the present invention is not limited to this, and any configuration may be adopted as long as the configuration can switch the connection state of the power line, such as a configuration including a switching element.
In addition, the above embodiments are merely examples of the embodiment of the present invention, and the technical scope of the present invention is not to be construed in a limiting manner. That is, the present invention can be implemented in various forms without departing from the gist or main feature of the present invention.
Industrial applicability
