Space-Grade Power Supplies Solutions

Space-grade power supply solutions are critical for ensuring operational reliability in the unforgiving conditions of orbital, lunar, and deep-space missions.
From radiation-hardened DC-DC converters to Class K-qualified modules and EMI filters, these components must meet rigorous performance standards across both Engineering Model (EM) and Flight Model (FM) phases.
Whether used in satellite constellations, scientific payloads, propulsion systems, or crewed space platforms, space qualified DC-DC power converters must deliver stable, efficient, and interference-free power in environments where failure is not an option.

Satellites (LEO, MEO, GEO)

Power systems for satellites must ensure stable voltage regulation for avionics, payloads, telemetry, and communication systems. In these orbits, where thermal cycling, vibration, and radiation vary significantly, hybrid DC-DC converters provide high efficiency and fault tolerance. Solutions are optimized for long-term missions with low failure tolerance, supporting Earth observation, navigation, defense, and telecom services.

Deep Space Probes & Scientific Missions

Missions targeting planetary exploration or deep-space research demand radiation-hardened and space-grade power supplies capable of withstanding Total Ionizing Dose (TID) exposure and Single Event Effects (SEE). These converters operate reliably over multi-year missions with no access for maintenance. Precision, thermal stability, and ultra-high reliability are essential for systems like scientific instruments, communication links, and propulsion subsystems.

Crewed Spacecraft & Stations

Life-critical systems aboard crewed spacecraft and orbital stations require power components that offer built-in redundancy, EMI compliance, and thermal robustness. Applications include life support, navigation control, instrumentation, and onboard computing. Modules must perform flawlessly under strict safety constraints and offer low noise and fault isolation to avoid system-wide disturbances.

Ground Testing & Environmental Simulation

Before launch, spacecraft systems undergo extensive validation using EM-equivalent models. Power supplies in these setups must replicate mission profiles, support hardware-in-the-loop simulations, and operate under thermal vacuum conditions. Precision control, programmability, and EMI performance are key for simulating real-world orbital stresses during qualification.

CubeSats & NewSpace Platforms

Cost-sensitive LEO missions often rely on COTS-based, radiation-tolerant solutions that offer a balance between performance and affordability. These platforms require compact, lightweight power converters with proven radiation mitigation and compatibility with small satellite buses. Typical applications include remote sensing, experimental payloads, and agile defense missions.
