Abstract

A high power drive stack system is provided which includes a cabinet ( 20 ) having a vaporizable dielectric fluid cooling system ( 110 ) and a plurality of receivers ( 22 ) for accepting a plurality of modules ( 30 ) containing power electronics. The modules are removably attachable to the receivers by at least two non-latching, dry-break connectors ( 210 ). Each of the at least two connectors providing both a fluid connection and an electrical connection between the cabinet and the module.
