Problems solved by technology

[0008] However, using IPM components according to the current design, the full advantages of SiC cannot be obtained due to oscillation problems that occur between the control part and the power semiconductor when the switching speed becomes high (greater than 10kA / μs)

Embodiment Construction

[0034] figure 1 The illustrated electrical switching apparatus 10 includes six electronic components 12 . Element 12 has a fast switching speed. The term fast switching speed is understood as a switching speed higher than 10 kA / μs or 20 kV / μs.

[0035] According to a preferred embodiment, the switching speed of element 12 is greater than 15 kA / μs (respectively, 30 kV / μs).

[0036] For example, elements 12 made of diamond, silicon carbide or gallium nitride have faster switching speeds.

[0037] For example, element 12 is a MOSFET transistor, a JFET transistor, or any other electronic element having the aforementioned switching speed.

[0038] Device 10 also includes a control circuit 14 or an igniter. The control circuit 14 is used to control the element 12 .

[0039] For example, the control circuit 14 can send commands to be applied to the input "gate" of the transistor.

[0040] according to figure 1 As an example, the control circuit 14 includes a plurality of contr...

Abstract

An electrical switching device includes at least two electronic components, with a control circuit designed to control the or each component. Each component is connected to the control circuit by a respective connection, and each component has a switching speed that is higher than 10 kA / mus or higher than 20 kV / mus and wherein the or each connection has an inductance that is lower than 10 nH.

Description

technical field [0001] The invention relates to an electronic switching device for electronic components with a high switching speed. The invention finds particular application in railway sections. Background technique [0002] Electronic components made of semiconductor materials with wide band gaps are now commercially available. For example, components made of silicon carbide or gallium nitride exist on the market. These components have lower losses and operate at higher switching speeds than components made from common materials. In addition, their junction temperature is usually high. [0003] It is desirable to use such elements in power converters because they provide gains in weight and volume and reduce electrical losses to a considerable extent. [0004] Components made of silicon carbide are used in several component types such as: diodes, MOSFET (Metal Oxide Semiconductor Field Effect Transistor) type transistors, or JFET (Junction Field Effect Transistor) ty...
