Project Description

Wide Temperature DC Link Capacitors for Aerospace Power Electronics Project Image
This project will develop advanced DC link capacitors using flexible ultrathin glass dielectric materials. The glass capacitor will be able to be operated in a broad temperature range (-150 degree C to 500 degree C), frequency (1 kHz to 1 MHz), and high voltage (>1,000 volts). This SBIR project will be focused on examining the technical performance of the glass dielectrics at very high (>200 deg C) and very low (<-100 deg C) temperature for NASA space missions with harsh and extreme environment. The performance under high radiation will also be evaluated as required by NASA. The effects of these extreme conditions on the glass dielectric and high voltage performance will be systematically examined in terms of dielectric constant, dielectric loss, dielectric breakdown strength, and leakage current.
