Readiness of SiC MOSFETs for Aerospace and Industrial Applications

This paper highlights ongoing efforts to validate performance, reliability and robustness of GE SiC MOSFETs for Aerospace and Industrial applications. After summarizing ruggedness and reliability testing performed on 1.2kV MOSFETs, two application examples are highlighted. The first demonstrates the 1.2kV device performance in a prototype high frequency 75kW Aviation motor drive. The second highlights the experimental demonstration of a 99% efficient 1.0MW solar inverter using 1.7kV MOSFET modules in a two-level topology switching at 8kHz. Both applications illustrate that SiC advantage is not only in improved performance, but also in significant system cost savings through simplifications in topology, controls, cooling and filtering.

Micro-Holograms Recorded in a New Thermoplastic Medium for Holographic Data Storage

This paper updates the recent progress in the micro-holographic format data recorded on a new dye-doped thermoplastic medium. The new medium is 400 times more sensitive than our first generation material. Characterization shows that micro-holograms can he written at a much faster rate
