DC-DC Converter Solutions
Micross Hi-Rel Power Solutions is a leader in power management solutions for high reliability and space applications. Located in San Jose, California, the facility is DLA certified Class K to design and manufacture ruggedized hermetic hybrid DC-DC converters. The group is supported by design centers in Herlev, Denmark for spacecraft power system designs and complex power conversion system solutions, and silicon design center in El Segundo, California. Decades of heritage in high reliability applications signify the company’s unwavering commitment to deliver nothing but the very best in power management solutions to the defense, aerospace, and space industries.
Our standard and radiation-hardened converters are at the heart of systems powering mankind’s most missioncritical applications. You’ll find us throughout the world and above it, in commercial and military aircraft, missiles, smart munitions, weapon systems, launch vehicles, LEO/MEO satellites, and GEO satellites.
Micross Hi-Rel Power Solutions’ steady thrust in crafting the best in technology with the best in technique for the industry has resulted in highly reliable solutions rich in innovation and unmatched in ability. Micross Hi-Rel Power Solutions’ new 89% efficient, all-hybrid Electronic Power Conditioner (EPC) developed for spacecraft is but one example.
