Abstract

The invention relates to a dual-layer laminated patch rectifying full bridge. The rectifying full bridge is designed by two layers of copper sheets and required crystal grains. Compared with the conventional rectifying full bridge formed by stacking five layers of copper sheets, copper materials are saved greatly, the cost of the rectifying full bridge is reduced, and the positioning of the crystal grains is more accurate and stable simultaneously, so the improvement on the rectifying effect of the rectifying full bridge is facilitated.

Description

technical field [0001] The invention relates to a rectifier bridge, in particular to a double-layer laminated patch type rectifier full bridge formed by cross-stacking and fixing crystal grains of double-layer KFC materials. Background technique [0002] The rectifier bridge module is a substitute for the bridge rectifier circuit composed of discrete rectifiers and silicon controlled rectifiers. The first generation of power electronic device products can be widely used in power electronic control equipment, such as inverter power supply, motor, speed control device, elevator control and other fields. Compared with the rectifier bridge circuit composed of discrete devices, the bridge module has the advantages of small size, convenient installation and high reliability. [0003] The pins and lead frames of the existing rectifier bridge are made of KFC copper. Due to the continuous rise in the price of copper, the production cost of the rectifier bridge continues to increase....
