Title:
HIGH POWER RECTIFIER BRIDGE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/024043
Kind Code:
A1
Abstract:
A high power rectifier bridge structure, comprising: first, second, third, fourth, fifth and sixth diode chips (2, 3, 4, 5, 6, 7) covered by an epoxy packaging body (1), a T-shaped connecting piece (8), a first L-shaped connecting piece (9), a second L-shaped connecting piece (10), a first strip-shaped connecting piece (11) and a second strip-shaped connecting piece (12). The T-shaped connecting piece (8) is located between the first L-shaped connecting piece (9) and the second L-shaped connecting piece (10), the first strip-shaped connecting piece (11) and the second strip-shaped connecting piece (12) are respectively located at two sides of the first L-shaped connecting piece (9) and the second L-shaped connecting piece (10), the first, third and fifth diode chips (2, 4, 6) are mounted on a support area of the first strip-shaped connecting piece (11), and the second, fourth and sixth diode chips (3, 5, 7) are respectively mounted on a support area of the first L-shaped connecting piece (9), the second L-shaped connecting piece (10) and the T-shaped connecting piece (8). The production labour efficiency of the high power rectifier bridge structure is increased by 8-10 times, the lead wire frame utilisation rate is increased by 10%, and a graphite crucible is not used in a structure welding process, thereby increasing the welding furnace energy utilisation efficiency.
