Technical Field

[0001] The utility model relates to the technical field of rectifier bridges, in particular to a semiconductor rectifier bridge. Background Art

[0002] A rectifier bridge is a rectifier tube enclosed in a shell. It is divided into full bridge and half bridge. A full bridge is to seal together the four diodes of a connected bridge rectifier circuit. A half bridge is to seal together half of a four-diode bridge rectifier. Two half bridges can form a bridge rectifier circuit, and a half bridge can also form a full-wave rectifier circuit with a center tap of the transformer. When choosing a rectifier bridge, you should consider the rectifier circuit and operating voltage.
