Abstract

The invention discloses an inline bidirectional electronic switch device based on a module IGBT, and the device comprises a high-frequency isolation coil which is electrically connected with a high-frequency driving power supply; the high-frequency isolation coil is in coupling connection with the double-on-off unit series-connection assemblies, the number of the double-on-off unit series-connection assemblies is N, N is larger than or equal to 1, each double-on-off unit series-connection assembly can independently achieve bidirectional through-flow, and the N double-on-off unit series-connection assemblies are connected in series. Each double-on-off unit series assembly can independently realize bidirectional through-flow, and a proper number of double-on-off unit series assemblies can be selected according to working voltage and current requirements, so that working requirements can be met. The electronic switch device is composed of a plurality of double-on-off unit series connection assemblies, the size of the electronic switch device can be controlled according to requirements, the unit assemblies are simple in structure, and maintenance difficulty is reduced.

Description

technical field [0001] The present application relates to the technical field of flexible direct current load current breaking, in particular to an inline bidirectional electronic switch device based on a module IGBT. Background technique [0002] The DC load switch is an important switching element of the DC power distribution system to ensure reliable switching of the DC load. Since the DC current has no natural zero-crossing point, the short-circuit current breaking of the DC system is more difficult than the AC breaking. Its breaking technology It is also a bottleneck problem restricting the development and promotion of DC power distribution system. [0003] The power semiconductor electronic switch is a key component of the DC load switch. It needs to withstand high voltage and high current, and control the on-off of the electrical circuit, that is, control the load current. The pros and cons of its quality and its control over the cost volume directly affect the perfo...
