Power Supplies Evolve to Meet Military Needs

Military electronics are continually pushing the boundaries of electrical design as these specialized components must prove reliable amidst harsh conditions. To ensure electronics deployed onboard a military platform, albeit airborne, ground or shipboard meet the military's rigorous demands, formal military standards are implemented to ensure the safety and effectiveness of equipment deployed in tactical operations.
One electrical component that must particularly keep pace with these growing demands is the subsystem power supply. Tasked with ensuring consistent reliable power to military computing devices - including mission computers and communications gear the power supply must meet MIL standard and application requirements, not to mention size, weight, and power (SWaP) constraints and cost considerations.
Military Standards 1275 and 704 (MIL-STD-1275 / MIL-STD-704) are of particular interest to vehicle electronics (vetronics) and aircraft engineers, respectively, when onboard subsystems are powered by a 24-V battery or 28-V generator. This article highlights aspects from these and related MIL standards with particular emphasis on the 1275 standard.
