Modular Power Architectures for Mission-Critical Electronics

High-reliability power conversion remains a core requirement in aerospace, defence, and industrial electronics, where voltage stability, electromagnetic compatibility, and fault tolerance directly affect system safety. At Embedded World 2026, held from March 10–12 in Germany, GAIA Converter is presenting several additions to its modular DC/DC and AC/DC portfolio aimed at mission-critical and harsh-environment platforms.

Power modules aligned with aerospace and military standards
Among the new releases is the HGMM-350 family of non-isolated AC/DC power-factor-corrected modules. These units are designed for aircraft and defence electrical networks where input quality and transient immunity are tightly regulated. The modules are engineered to meet harmonic distortion and transient requirements defined in DO-160, MIL-STD-704, and ABD100, standards that govern airborne equipment power interfaces and military aircraft electrical systems. Compliance at this level supports integration into avionics subsystems, radar electronics, and airborne mission computers that must tolerate voltage spikes, frequency variations, and conducted disturbances.

GAIA Converter is also showing the MGDM-500/P, a parallel-capable version of the MGDM500 series. By enabling multiple modules to operate together, system designers can scale output power up to 3 kW while preserving efficiency and redundancy. Parallel architectures of this type are commonly used in mission systems where load sharing and graceful degradation are required, such as ground-based defence electronics and rugged communication nodes.

Additional introductions include the PSDG-48, a fully integrated COTS multi-output 48 W isolated board-mount supply for 24 Vdc and 28 Vdc military buses, and the MGDS300S, which extends both output power and voltage range within the MGDS family of high-density, wide-input DC-DC converters. These formats address distributed power architectures in rugged embedded systems, where board space is limited and multiple regulated rails are needed close to processing or sensor loads.




Configurable COTS platforms for faster system integration
Beyond individual converters, the exhibition also highlights the GRD Series of configurable military-grade COTS power supplies spanning 120 W to 500 W. These assemblies illustrate how pre-engineered building blocks can shorten development cycles in defence and aerospace programs that operate under strict qualification constraints.

The GRD-12 is a configurable reference design board delivering up to 120 W across three main outputs and two auxiliary rails. It is based on modules from the MGDD series and serves as a demonstration platform for multi-output architectures in compact embedded equipment.

At higher power levels, the GRD-40 family provides 400 W low-profile supplies with integrated EMI filters, reverse-polarity protection, inrush current limiting, and input surge limiting. These protection and filtering stages are typically required to meet military vehicle and aircraft power interface standards, reducing the need for additional front-end circuitry at the system level.

The GRD-50 series extends this approach to 500 W integrated supplies optimized for 24 Vdc and 28 Vdc input environments. Such voltage rails are standard in ground vehicles, aircraft, and naval platforms, where robust front-end design helps maintain reliability under load dumps, cold starts, and line transients.

Modular power in mission-critical electronics
Across these product families, the emphasis is on modular power conversion that supports scalable architectures and compliance with established aerospace and military electrical standards. This approach aligns with the needs of rugged embedded systems used in defence platforms, avionics, and industrial equipment exposed to vibration, temperature extremes, and unstable input power conditions.
