New power module concept by forced-air cooling system for power converter

Power electronic converters use power semiconductor devices. By improvement of the device performances, the electric power density, defines as ratio of converter output power and converter volume, is continuously increased. However, volume of the Cooling System to occupy a substantial portion of power electronic converter, therefore improvement of the Cooling System performance is one of the important problems. In this paper, optimized forced-air cooling system and new power module design concept are introduced.
