Patent ID: 7804689

Claim:
A high-power thyristor module comprising: a housing configured with an inner receiving space; a thyristor unit disposed in said inner receiving space in said housing, said thyristor unit including a mounting frame, and a plurality of high-power thyristors mounted on said mounting frame, each of said thyristors having a gate, said mounting frame including a dielectric top plate disposed on a top side of said housing, and a plurality of electrodes mounted on said top plate so that said electrodes are exposed outwardly of said housing, and coupled respectively to said gates of said thyristors; cooling oil contained in said inner receiving space so that said thyristors are submerged thereby; wherein said mounting frame of said thyristor unit further includes a dielectric bottom plate disposed under said top plate and spaced apart from said thyristors; and wherein said thyristor unit further includes a plurality of heat sink units each disposed fixedly on said bottom plate for dissipating heat generated by a corresponding one of said thyristors.
