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 an in-line single-phase three-phase compatible rectifier bridge stack, which includes an insulating casing, wherein at least four frames are arranged in the insulating casing, at least two conductive chips are arranged on the frame, and a first connecting chip is arranged in the insulating casing. The jumper and the second connection jumper, the first connection jumper and the second connection jumper are respectively electrically connected to the conductive chip, the frame is also connected to the lead pin, and the first connection jumper is connected to the frame on the left side of the insulating shell , the second connection jumper is connected to the frame on the right side of the insulating shell. The beneficial effects are: 1. Solve the compatibility of the rectifier power supply in single-phase and three-phase power environments, and make few changes to the bridge stack. Realize the compatibility of single-phase rectification and three-phase rectification; 2. Adopt GPP chip to increase the current capacity from the original 35A to 55A.
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...
