Applications
The Industries We Serve
Six markets, one engineering standard. Select an application to see the qualification envelope, product families and the standards our design teams work to every day.
Military-Grade Modules and Power Systems
The MilQor® line brings SynQor's field-proven synchronous-rectifier technology to defense and aerospace programs. Designers get a single-source chain — EMI filter, PFC front end, isolated DC-DC bus converter and point-of-load regulation — already characterized together, which removes the integration risk that normally appears during EMC qualification.
- MIL-STD-704 (A-F)
- MIL-STD-461 (C-F)
- MIL-STD-1275
- MIL-STD-1399
- MIL-STD-810G
Medical AC-DC and DC-DC Power Supplies
High power-density, medical-grade converters with a wide selection of output voltages and power levels. Low leakage current and ed. 4.0 EMC performance are designed in from the start, so imaging, diagnostic and patient-contact equipment clears agency testing without bolted-on mitigation.
- EN 60601-1
- IEC 60601-1-2 ed. 4.0
- EN 61000-3-2 Active PFC
- 2×MOPP options
Ruggedized Industrial Converters and Filters
Built for motion control, information displays, fuel cell units, factory automation and distributed power generation. The two-stage topology with synchronous rectification keeps dissipation low at full load, which is what allows sealed and conduction-cooled industrial enclosures to run without forced air.
- Wide input range
- Conduction cooling
- Extended temperature
- Fuel cell ready
RailQor® Rolling-Stock Power Conversion
The RailQor® series supplies isolated DC power to LED displays, audio amplifiers, safety monitors, lighting and on-board communications under EN 50155. Shock, vibration, wide temperature swings and unstable catenary voltage are treated as the baseline operating condition, not an exception.
- EN 50155
- EN 50121-3-2
- Class S2 / C1 hold-up
- 24 – 110 Vdc nominal
AeroQor® Airborne AC-DC Conversion
Isolated AC-DC converters and AC line filters engineered for airborne power buses. Power factor correction, wide-frequency 400 Hz operation and controlled inrush let line-replaceable units meet RTCA/DO-160 alongside Airbus and Boeing platform specifications.
- RTCA/DO-160G
- Airbus ABD0100
- Boeing 787B3-0147
- 360 – 800 Hz
Telecom and Datacom COTS Modules
Industry-leading bus converters and point-of-load modules for LAN and WAN equipment, signal amplifiers, base stations and data centers. Higher conversion efficiency directly lowers rack-level heat load and total cost of ownership across a 48 V distributed architecture.
- -48 Vdc telecom input
- Quarter / eighth brick
- Industry standard pinout
- High MTBF
Quality & Reliability
Designed to Meet the Highest Quality and Reliability Standards
SynQor's process-centered organization structure enforces the same discipline through design, qualification and manufacturing — so the unit shipped in year ten behaves like the unit qualified in year one.
Exceeding ISO-9001 and AS9100 quality standards
Documented process control, traceability and qualification records that stand up to prime-contractor audits.
Designed and manufactured in our U.S.-based facility
Salem, New Hampshire engineering and production keeps the supply chain short, visible and program-compliant.
A legacy built on innovation that continues today
From commercializing synchronous rectification to field-grade 3-phase UPS, the roadmap keeps extending the efficiency curve.
Engineering Experience
Why Program Engineers Specify SynQor
Selecting a converter is a thermal, EMI and lifecycle decision — not just a data-sheet comparison. These are the three factors our application engineers review most often with OEM design teams.
Synchronous rectification lowers heat, not just loss
Replacing output diodes with actively driven MOSFETs removes fixed forward-voltage loss. At high output current that difference becomes watts of avoided dissipation, which shrinks heatsinks, allows sealed enclosures and improves component-level reliability margins.
Filter and converter qualified as one chain
Most EMC failures appear at the interaction between the input filter and the converter. Because SynQor supplies both, conducted-emission and transient performance is characterized together — shortening the MIL-STD-461 and DO-160 test cycle.
Built for multi-decade platform support
Defense, rail and industrial platforms outlive commercial component cycles. Long product lifecycles, form-fit-function replacement paths and archived qualification data protect programs from unplanned redesign.

Buyer & Designer FAQ
Common Questions From Power System Designers
SynQor pioneered the commercial use of synchronous-rectifier technology in isolated DC-DC converters. Replacing lossy diodes with actively driven MOSFETs, combined with a two-stage power topology, lowers conduction losses and power dissipation. The result is higher efficiency, reduced thermal stress and longer field life in sealed or conduction-cooled enclosures.
SynQor modules and systems are engineered against MIL-STD-704 (A-F), MIL-STD-461 (C-F), MIL-STD-1275, MIL-STD-1399, MIL-STD-810G, RTCA DO-160G, EN 50155 for rail rolling stock, EN 61000-3-2 for power factor, and EN 60601-1 / IEC 60601-1-2 ed. 4.0 for medical equipment.
Engineering, qualification testing and manufacturing are performed at SynQor's U.S.-based facility in Salem, New Hampshire, under a quality management system that exceeds ISO-9001 and AS9100 requirements — giving program managers full supply-chain traceability.
Yes. SynQor supports multi-decade defense, rail and industrial platforms with long product lifecycles, form-fit-function replacement strategies, documented qualification data and direct access to application engineers for derating, thermal and EMI analysis.
