Description
Technical Field
[0001] The utility model relates to the technical field of electronic equipment, in particular to a high-safety embedded rectifier bridge. Background Art
[0002] The rectifier bridge generally carries a sufficiently large inductive load, so there is no current discontinuity in the rectifier bridge. When the rectifier bridge is generally used, a smoothing inductor is often connected to its load end, so its load can be regarded as a constant current source. Multiple groups of three-phase rectifier bridges are connected to each other so that the harmonics generated by the rectifier bridge circuit cancel each other out. According to the type of rectifier transformer, it can be divided into a traditional multi-pulse transformer rectifier bridge and an autocoupled multi-pulse transformer rectifier bridge.
[0003] Most of the existing embedded rectifier bridges encapsulate the rectifier tube in a shell. This installation method results in poor heat dissipation of the rectifier bridge, which is prone to overheating and damage during operation, and has low safety in use.
