Multifunctional rectifier bridge jumper system

Abstract

The invention discloses a multifunctional rectifier bridge jumper system. The system comprises a first working part, a connecting part and a second working part connected into a whole, wherein the first working part is used for being connected with a grain, the second working part is used for being connected with a framework, the top face of the first working part is parallel to the top face of the second working part, the top face of the first working part is provided with a groove, and the bottom face of the first working part is provided with a boss. According to the system, by redesigninga jumper of a GBU rectifier bridge product, the VF of the product is lowered, the effective welding area of the grain is enlarged, the forward surging capability of the product is improved, and the effects of reducing product stress, lowering product power consumption, lowering product thermal resistance and improving product reliability are achieved.

Description

technical field [0001] The invention relates to a modification of a jumper system of a multifunctional rectifier bridge. Background technique [0002] When welding the GBU rectifier bridge products, four identical jumpers will be used. The traditional jumper design, the design of the soldering point between the jumper and the die is too small to fully reflect the actual VF (forward voltage) of the die itself. Ability, resulting in high VF, poor heat dissipation, and high thermal resistance of the product, resulting in poor reliability during production and use, and cannot meet the product development trend of low power consumption and high reliability. [0003] During the anatomical analysis of the client GBU rectifier bridge failure products, the applicant found that for almost all the failure products, the breakdown point on the product die was located at the position where the jumper and the die were not soldered, indicating that the traditional jumper The line design wi...

[0002] When welding the GBU rectifier bridge products, four identical jumpers will be used. The traditional jumper design, the design of the soldering point between the jumper and the die is too small to fully reflect the actual VF (forward voltage) of the die itself. Ability, resulting in high VF, poor heat dissipation, and high thermal resistance of the product, resulting in poor reliability during the production period of the product, which cannot meet the product development trend of low power consumption and high reliability.

[0003] During the anatomical analysis of the client GBU rectifier bridge failure products, the applicant found that for almost all the failure products, the breakdown point on the product die was located at the position where the jumper and the die were not soldered, indicating that the traditional jumper The line design will affect the forward capability of the product, resulting in high power consumption and high temperature rise during the long-term use of the client, making it unable to withstand large forward surge currents
