Problems solved by technology
Therefore, if the gate substrate is to be arranged near the semiconductor element, the shape of the smoothing capacitor becomes complicated
Because the P and N thin-plate conductors 7 are arranged on the front surface of the semiconductor element, it is difficult to approach the gate of the semiconductor element.
[0009] In addition, the power conversion part 2A of the vehicle control device includes a brake chopper part, and the structure of the brake chopper part is different from that of other power conversion parts. , the wiring route partially interferes with the brake chopper, so that the ideal shortest gate wiring between the gate substrate 3A and the control unit 4 cannot be realized.

Embodiment Construction
[0023] Hereinafter, the present invention will be described in detail based on the illustrated preferred embodiment. Fig. 1 is in order to illustrate the structure of embodiment 1 of the present invention, cut horizontally near the mounting end to the vehicle body, and observes the sectional view from the mounting side to the vehicle body, Fig. 2 is its A-A arrow sectional view. In the figure, the same reference numerals are assigned to the same elements as in FIG. 9 showing the conventional device, and description thereof will be omitted.
[0024] In each figure, the power conversion part 2B is mainly composed of a semiconductor element and its cooling device 14, and the P and N thin plate conductors 7 are arranged away from the power conversion part 2B, and are fixed to the P and N connection terminals with the power conversion part 2B by a plurality of screws. 7a on. The smoothing capacitor 6 arranged on the opposite side to the power conversion unit 2B is also connected t...

PROBLEM TO BE SOLVED: To provide a controller for a vehicle which is hardly affected by an influence of an electromagnetic noise by most shortening a semiconductor element gate of a power conversion unit, gate wiring between a gate substrate and a control unit. ŽSOLUTION: The controller for the vehicle includes the power conversion unit 2B containing the semiconductor element, a smoothing capacitor 6, a conductor 7 of a thin plate structure for electrically connecting the power conversion unit 2B and the smoothing capacitor 6, a gate substrate 3A for driving the gate of the semiconductor element, the control unit 4 for controlling the gate substrate, and the gate wiring 5B for electrically connecting between the gate substrate and the control unit, individually contained in a case 1 installed under a floor of a railway vehicle for forming a sealed chamber to perform a power conversion by switching the semiconductor element. A gate substrate connector 3B for connecting the gate substrate 3A is disposed to a position deviated to side of the one vehicle body from a center of a sleeper direction of the sealed chamber, and the gate wiring is connected to this gate substrate connector.

Description
technical field [0001] The present invention relates to a vehicle control device. Background technique [0002] The vehicle control device is mainly composed of a power conversion unit including a semiconductor element for electronic conversion, a cooling device, a power source, a gate substrate of the semiconductor element, a smoothing capacitor, and the like, and a control unit that controls the power conversion unit. [0003] The gate wiring between the power conversion unit and the control unit is led out to the back side of the power conversion unit, leads to the back side of the control unit arranged in parallel with the track direction, and is connected to the front surface of the control unit. Such a wiring route is much longer than the ideal shortest distance when connecting the power conversion part and the control part. Since the gate wiring is more susceptible to electromagnetic influence as the wiring length is longer, it is necessary to provide a core wire on ...
