Triaxial double switch module

摘要

A low inductance triaxial semiconductor switching module. The module permits high power semiconductor switching devices to operated at high frequency but with low inductance. The module incorporates compositional, geometrical and electrical symmetry in connection with a triaxial terminal subassembly having coplanar contact areas. The terminal subassembly is readily fabricated and assembled into the module. The module also includes short internal leads, a special circumferential array of substrates subassemblies, and a circular circuit board having gate and Kelvin circuit patterns.
