Electronic power semiconductor module for use in power-electronic unit to start electrical engine, has partial bodies stacked on each other such that bodies are fixed to each other and semiconductor elements are supplied with pressure

摘要

The module has three cylindrical partial bodies (11-13) provided with a pressing device and two power semiconductor elements (23, 26). The partial bodies are stacked on each other such that the partial bodies are fixed to each other and the power semiconductor elements are supplied with pressure. The partial bodies are provided with cooling ribs on a lateral surface, where the cooling ribs run toward a vertical axis. Two of the partial bodies (11, 12) are provided with plastic enclosed gate terminals (41).
