High Temperature Capacitors for Venus Exploration, Phase I

Completed Technology Project

Project Introduction

High Temperature Capacitors for Venus Exploration, Phase I
High temperature power electronics have become a vital aspect of future designs for power converters in spacecraft, battle zone electric power, satellite power conditioning, and well drilling. The performance of these applications would benefit significantly from materials designed for high temperatures and harsh environmental conditions. NASA's Venus mission has some of the most stringent requirements with an operating temperature of 486C. Power systems must operate efficiently at these temperatures to eliminate the need for onboard cooling systems. The removal of these cooling systems will save space, reduce weight, and improve reliability. Currently, BaTiO3-based X7R capacitors are re-rated for use above 125C, and are rendered inoperable at temperatures approaching 300C. NPO-type dielectrics tend to operate at somewhat higher temperatures, but have low dielectric constants and become unreliable above 400C. TRS Technologies is pleased to respond to NASA's need for high temperature capacitors with this Phase I SBIR proposal. In this SBIR program, TRS Technologies and its subsidiary, Centre Capacitor, will develop a new family of high temperature capacitors based on high Curie temperature ferroelectrics that operate at temperatures far beyond conventional dielectric formulations. These new higher temperature (~490C) materials will be suited for the advanced power electronics required for Venus exploration. More »
