摘要： PURPOSE:To allow high response operation of a current control system by passing only one polarity of an input to the current control system for controlling the output current from an inverter based on an idling/slip detection signal and then controlling the output from the inverter depending on the output from the current control system. CONSTITUTION:A current control system normally operates to match the output current Im from an inverter 2 with a command value. In other words, output frequency of the inverter 2 is increased when the output current Im is low whereas the output frequency of the inverter 2 is decreased when the output current Im is high. Upon occurrence of idling, only one polarity of input to the current control system is operated by an idling/slip detection signal WSD. In other words, the current control system does not operate when the output current Im is lower than a current command Im* and the current control system operates to decrease output frequency of the inverter 2 when the output current Im is larger than the command Im*. This constitution allows high response operation of the current control system even during readhesion interval upon occurrence of idling or slip.

摘要： PURPOSE:To achieve miniaturization of a device including a cooler system as a whole by a method wherein a semiconductor switching element for a main circuit is mounted on one face of a heat-receiving plate and a heat pipe is buried into the other face. CONSTITUTION:Heat-receiving plates 31, 32 are attached so as to constitute one part of the outer wall of an enclosure 6 which houses constituent components for an inverter apparatus for an electric train. Semiconductor switching modules SM1 to SM4 are mounted on faces, one one side, of the heat-receiving plates 31, 32, the straight part, one one side, of a heat pipe 51 which has been bent to be L-shaped is buried into faces on the other side, and a radiating fin 52 is attached to the straight part, on the other side, of the heat pipe 51. Thereby, a cooling device is constituted. Since the semiconductor switching modules SM1 to SM4 are not turned on at the same time, the amount of heat entering the heat-receiving plates 31, 32 is made uniform. Thereby, coolers 53, 54 can be made small-sized. Especially when they are mounted on the lower part of the floor of an electric train, their cooling efficiency can be increased when the heat-receiving plates 31, 32 are attached so as to constitute one part of the vertical outer wall face, along the traveling direction of the electric train, of the enclosure 6.

摘要： PURPOSE:To attenuate electromagnetic induction noise, by arranging the load output wires of an inverter close to each other. CONSTITUTION:Semiconductor elements composing an inverter are contained in a cooling unit 5, and the load output terminals U-W of each phase are arranged as one group, and plus and minus terminals connected to a power source are arranged as another group. Then, by arranging wires from the output terminal 4 of the cooling unit to an out-fit terminal 2, close to each other, electromagnetic induction noise generated from the output wires of each phase can be attenuated.

摘要： PURPOSE:To miniaturize the title device and lighten its weight, by dividing a filter circuit into a plurality, and by using optimum instruments for necessary specifications. CONSTITUTION:Power fed from a DC power source 1 is fed to a main motor 2 via a filter circuit and a switching element 3. Then, a filter condenser 7 must be worked according to voltage fluctuation at a point A, and so the oil condenser excellent in high frequency characteristic is used. By a filter condenser 5, voltage fluctuation at a point B is reduced, and so for the condenser 5, the electrolytic capacitor of a capacity larger than that of the oil condenser in case of the same volume is used. For filter reactors 4 and 6, the filter reactor 4 is provided with an intermediate tap. As a result, a filter can be miniaturized and the weight can be lightened.

摘要： PROBLEM TO BE SOLVED: To provide a power converter capable of suppressing the wiring length of a main circuit and that of a snubber circuit to the minimum, and capable of having small-sized simple mounting structure. SOLUTION: A module type power semiconductor devices 1A, 1B incorporating self-arc-extinguishing semiconductor devices and snubber capacitors have the collector terminals C and the emitter terminals E1 of the self-arc- extinguishing semiconductor devices, and the anode terminals A and the cathode terminals K of the snubber diodes provided independently respectively, and they are arranged in such a way that the collector terminals C and the emitter terminals E1 may be on both sides of the anode terminals A and the cathode terminals K of the snubber diodes. As the result of this, it becomes possible to cause the module type power semiconductor devices 1A, 1B to have the same terminal arrangement, and besides to linearize and simplify wiring by a positive electrode P side wiring member 4, a negative electrode N side wiring member 5, and a wiring member 6 for AC output, and to simplify the connection with a snubber capacitor module 2 also.

摘要： PURPOSE:To reduce a poor influence due to harmonic current generated by a power converter by connecting a cooling means to the grounding side of the power supply of a switching element via an insulator. CONSTITUTION:Heating plates 18a and 18b are mounted to an enclosure 20 of an inverter device via a sufficiently thick insulator 17 such as rubber and then the heating plates 18a and 18b constituting a cooling equipment are directly connected to the minus line of a main circuit. With this configuration, harmonic current reaching an induction motor 10 is bypassed by the electrostatic capacity of switching elements 41a, 42a, 41b, and 42b and a conductor 91 and directly returns to a filter capacitor 7, thus preventing the harmonic current from being leaked to the outside of the inverter device 20. Therefore, since the harmonic current flowing to the conductor connecting the inverter device 20 and the induction motor 10 can be reduced, the conductor plays a role of an antenna, thus preventing induction fault from being induced.
