Abstract
Demonstration of a cryogenically cooled electronic power converter/inverter exhibiting a throughput power of at least 50 kW is proposed. The demonstration topology may be utilized as a variable amplitude variable frequency dc-to-ac inverter, or as a polyphase ac-to-dc rectifier. Operation of the prototype is to be at a temperature of 77 degrees K utilizing liquid nitrogen as a coolant. The project seeks not only to demonstrate the operation of a cryogenically cooled converter, but also to address key technical issues in the optimization of such power electronics modules for full-scale installed systems utilized in airborne and ground-based airborne support. ASC has demonstrated a 100kW CryoPower*TM inverter using commercial power electronic devices. The functional requirements and specifications for commercial devices are less severe than those for defense power systems. We will provide the Air Force with a 50kW CryoPower converter/inverter designed to Air Force requirements.
