Problems solved by technology
[0004] Question 1: In the rectifier power supply, because the appearance of the single-phase rectifier bridge and the three-phase rectifier bridge are very different, when the rectifier bridge is replaced, the welding holes of the line pins will not match. For example, single-phase products are generally welded. The phases are generally plugged or screwed, resulting in line mismatch problems
[0005] Question 2: For the single-in-line rectifier bridge, the rated rectification current is 1A to 35A, the current is too small, and it cannot be applied to places that require higher current

The invention specifically relates to a direct-insert rectifier bridge compatible to single-phase rectification and three-phase rectification. The direct-insert rectifier bridge includes an insulation shell inside provided with at least four frames. The frames are provided with at least two conducting chips. The insulation shell is inside provided with a first connection jumper and a second connection jumper connected with the conducting chips electrically. The frames are also provided with terminal pins. The first connection jumper is connected to the frame on the left side of the insulation shell while the second jumper is connected to the frame on the right side of the insulation shell. The invention has beneficial effects that (1) compatible use of a rectification power source in a single-phase power environment and a three-phase power environment is realized and the compatibility of single-phase rectification and three-phase rectification is achieved with slight change of the rectifier bridge; (2) current capacity is increased to 55A from 35A by adopting a GPP chip.
Description
technical field [0001] The invention specifically relates to an in-line single-phase three-phase compatible rectifier bridge stack. Background technique [0002] At present, the rectifier bridge is widely used in electronic and electrical products because of its reliable operation and convenient installation. According to the different use environments of the rectifier bridge, it is divided into single-phase rectifier bridge and three-phase rectifier bridge. The single-phase rectifier bridge is mainly a single-in-line structure, while the three-phase rectifier bridge is mainly a module structure. Big difference. [0003] The existing rectifier bridges face many practical problems in terms of operability. [0004] Question 1: In the rectifier power supply, because the appearance of the single-phase rectifier bridge and the three-phase rectifier bridge are very different, when the rectifier bridge is replaced, the welding holes of the line pins will not match. For example, s...
