POWER ELECTRONICS

E2TAC researchers have developed integrated cryogenic power modules for use in high-performance inverters.  Specific areas of E2TAC R&D include: 

• Cryogenic qualification of packaging components and materials (substrates, die-attach, wire bonds, encapsulation)
• Thermal, mechanical, and electrical modeling of power components at cryogenic temperatures
• Design and prototyping of integrated power modules followed by qualification and testing
• Fabrication of integrated modules for cryo-inverter demonstrations
• 3-D packaging development with goal to eliminate wire bonds and increase reliability

Novel Power Electronics Devices

E2TAC is using numerical simulations and proof-of-principle experimentation to investigate the potential of new high-performance device designs that are intended to provide superior I-V characteristics to current power MOSFETs or IGBTs used in power electronics.
