Then, the conductor that control circuit busbar is shown in FIG. 6 is constituted.As shown in fig. 6, control circuit busbar 12
Each conductor is constituted by being respectively arranged at the conplane poles G conductor 121~126 and the poles E conductor 127~132, from away from switch module
Side (nearby side) stacks gradually the poles E conductor 127~132, the poles G conductor 121 towards close to switch module side (inboard) farther out
~126.
Here, the switch module 21 of the module connection of the poles E conductor 127,129, the 131 extreme sons 941 of E and positive voltage side,
23,25 emitter control terminal 741 connects, module the connection extreme sons 931 of E and the negative voltage of the poles E conductor 128,130,132

Since the poles E conductor 127,129,131 and the poles M conductor 113,114,115 are respectively same current potential, thus structure as previously described
It is adjacent with the poles the E conductor of control circuit busbar 12 across insulating trip as the poles the M conductor 113~115 of main circuit busbar 11.
The effect and effect can be described in detail below, but according to the configuration, can inhibit in main circuit busbar 11 and control
The generation of insulation breakdown and noise being worried between circuit busbar 12 processed, caused by high electric field.
The through hole 814 of the poles N conductor, the through hole 822 of the poles M conductor, main circuit insulating trip through hole 832 be set to

As described above, the poles M conductor 113~115 is adjacent to stacking across insulating materials with control circuit busbar 12.
In the case that potential difference between the busbar adjacent across insulating materials is more than the insulation pressure resistance of insulating materials, insulation material will produce
The insulation breakdown of material flows larger electric current between busbar.In addition, even if be less than insulation pressure resistance in the case of if by
In there are parasitic capacitances between busbar, if therefore potential difference it is larger, electric current is flowed through via the parasitic capacitance, to control
Noise is generated in circuit processed.By matching as in this embodiment by the poles M conductor 113~115 is adjacent with control circuit busbar 12
It sets, so as to inhibit the generation of insulation breakdown and noise caused by high electric field as described above.
Illustrate the mechanism for generating the effect below for 1 phase being made of switch module 21 and 22.It is false herein
The low potential side for determining power supply is 0V, hot side 1500V.Low potential is being exported from opposite load connection M extreme sub 921
In the case of, the switch module 21 of upper arm becomes (OFF) state of disconnection, and the switch module 22 of underarm becomes (ON) state of connection,
The low potential side of power supply is connected with load connection M extreme sub 921.In this case, the emitter of the switch module 22 of underarm
Control terminal becomes the same current potential of emitter side with switch module 22, and current potential becomes 0V.In addition, the hair of the switch module 21 of upper arm
Emitter-base bandgap grading side also becomes the same current potential of low potential side with power supply, therefore the current potential of the emitter control terminal of switch module 21 also becomes
0V.Therefore, in the case where exporting low potential, the emitter control of the emitter control terminal, switch module 22 of switch module 21
Terminal processed, load connection all become 0V with the current potential of the extreme sons of M 921, do not generate potential difference, therefore the above problem will not occur.
Then, in the case of 921 output high potential of son extreme with M from the opposite load connection, the switch module of upper arm
21 are turned on, and the switch module 22 of underarm becomes off-state, and the hot side of power supply and load connection are extremely sub with M
921 connections.In this case, the emitter control terminal of the switch module 21 of upper arm becomes and load connection M extreme sub 921
Same current potential, current potential become 1500V.On the other hand, the emitter control terminal of the switch module 22 of underarm becomes low with power supply
The idiostatic 0V in current potential side.Therefore, in the case where exporting high potential, the emitter control terminal of switch module 21, load connect
Connect becomes 1500V with extreme sub 921 current potentials of M, and the emitter control terminal of switch module 22 becomes 0V, it is possible to occur above-mentioned
Problem.
Here, illustrating the structure for solving the problems, such as above-mentioned potential difference in the case where exporting high potential using Fig. 8
At.Fig. 8 show the poles the M conductor 113,114,115 that is adjacent to across insulating materials and the poles E conductor 127,128,129,130,
131,132 configuration relation.As shown in figure 8, the poles M conductor is configured at the emitter control terminal of the switch module 21 of covering upper arm
741 position, and be laminated with the poles the E conductor 127,129,131 that is connect with switch module 21, but it is not configured at the switch with underarm
The 741 corresponding part of emitter control terminal of module 22, and the poles the E conductor 128,130,132 being connect with switch module 21 is not
Stacking.
Become idiostatic with when high potential exports and when low potential exports by being like this configured at the poles M conductor
The poles E conductor 127,129,131 is laminated and is not laminated with the poles the E conductor 128,130,132 for generating potential difference when high potential exports
Position, ensured to insulation distance.By such composition, even if to main circuit busbar 11 is electric with control
Road busbar 12 be laminated be integrated component in the case of, can also solve due to the influence from main circuit busbar
And causes to lead to the problem of noise in control circuit busbar or insulation breakdown occurs.
In addition, when high potential exports, due between the poles the E poles 127,129,131 and E of conductor conductor 128,130,132
High potential difference is generated, therefore between these conductors it is expected that sufficient insulation distance is arranged or insulating materials is set.
In addition, in the present embodiment, illustrating by making the poles M conductor with the poles E conductor 127,129,131 across insulation material
Material is adjacent to stacking, to solve the problems, such as in control circuit busbar generation noise or there is a situation where insulation breakdowns, but
It is non-compared with main circuit power voltage since gate control terminal and the potential difference of emitter control terminal are 10~20V degree
It is often small, therefore even if exchanging the position relationship of the poles E shown in fig. 6 conductor and the poles G conductor, be set as making the poles M conductor and the poles G conductor
121,123,125 are adjacent to stacking across insulating materials and are configured at the poles M conductor and are not laminated with the poles G conductor 122,124,126
Position structure, can also obtain substantially same effect.That is, this is because the poles M conductor and the poles G conductor 121,123,125
Potential difference as low as 10~20V degree when high potential exports and when low potential exports, the poles M conductor and the poles G conductor 122,
124,126 potential difference is greatly to the reason of 1480~1490V degree.
If as described above, using the composition of the one-piece type busbar enumerated in the present embodiment, main circuit can be converged
Stream item is engaged with control circuit busbar and accumulates a component, and insulating properties, assemblability and resistance to are as a result capable of providing
The power-converting device that noise-induced is ensured.
In the present embodiment, used as switch module have 2 switch elements in parallel and have 2 collectors/
The switch module of emitter terminal, but can also apply to have the switch module of switch element or have 3 and in parallel open
Close the switch module of element.
