New Technologies and Concepts for Low Loss Radiation Hardened DC/DC Converters

Abstract

Two new low loss radiation hardened technologies for DC power conversion are reported: a pulse width modulator and a digital isolator. Both are shown to be superior to currently available components used in radiation hardened DC/DC converters in terms of both power efficiency and radiation hardness. A method for combining the two technologies to maximize their benefit in DC/DC converter applications is described.
