An efficient configuration for a power system is provided, e.g. for high-spe ed source transfer, utilizing power electronic assemblies and a directed ventilation arrangement. Each power electronic assembly includes a plurality of stacked power electronic device modules that are electrically series connected and energized at various voltages. Each power electronic device module includes two heat sinks, a power electronic component assembly interposed between the two heat sinks, and an arrangement for clamping the heat sinks a nd the power electronic component assembly. In a preferred embodiment, the power electron ic component assembly includes two stacked, series connected power electronic components such that single-sided cooling is provided. In one application, the power-electronic components are thyristors that have a high short-term, fault-current rating and a relatively low avera ge current requirement. This arrangement provides a reduced height configuration along with the advantages of modular clamping for ease of assembly, simplicity of component s, ease of maintenance and overall reliability of components.
