Abstract

The invention relates to a silicon controlled rectifier module. The silicon controlled rectifier module comprises a red copper bottom plate and a shell which is arranged on the red copper bottom plate; the left end and the right end of the red copper bottom plate are each provided with an external hole; the red copper bottom plate is provided with two ceramic chips between the two external holes;the two ceramic chips are respectively provided with a group of copper-clad areas; each copper-clad area is provided with a group of extraction electrode plates and two chips according to a controllable rectification circuit, and gate poles are arranged in the middle of the chips; and aluminum wires are bonded between the chips and the copper-clad areas and between the gate poles and the copper-clad areas. The silicon controlled rectifier module can effectively solve the problems that an existing silicon controlled rectifier module is connected through a connecting bridge, stress is high, a chip is prone to damage, and the service life is shortened.

Description

technical field [0001] The invention relates to a thyristor module. Background technique [0002] In the prior art, the structure of the thyristor rectifier module basically includes a shell, and components such as lead-out electrode sheets, copper connecting plates, bridges, controllable chips, ceramic copper-clad laminates, and copper bottom plates set in the shell, At the same time, lead out electrode sheets, copper connection plates, connecting bridges, controllable chips, ceramic copper clad laminates and copper bottom plate groups are encapsulated in the housing by epoxy resin. [0003] However, the connection through the bridge method has the problems of high stress, easy damage to the chip, and shortened service life. Contents of the invention [0004] The object of the present invention is to provide a thyristor module, which solves the problems that existing thyristor modules are connected through a bridge, which has high stress, easily damaged chips, and shorte...
