Abstract
The stackable power semiconductor module comprises electrically conductive base plates, an electrically conductive cover plate and a plurality of semiconductor chips. The semiconductor chips are arranged in groups of several on separate base plates in preassembled submodules. The base plates are moveable towards the cover plate. The submodules are paralleled inside the module housing. The submodules are fully testable according to their current ratings. Altering the number of submodules paralleled inside the housing can vary the overall current rating of a module.
