Explore our certified range of isolated DC-DC converters, active PFC front-ends, anti-corrosion UPS, and ruggedized power supplies exported across the Iberian Peninsula.
A comprehensive analysis of loss-mitigation mechanics, power density limits, and thermal management in modern high-reliability DC-DC and AC-DC power converters.
Traditional secondary-side power conversion relies on Schottky barrier diodes, which present a fixed forward voltage drop ($V_F \approx 0.4\text{V} - 0.7\text{V}$). At elevated current outputs (e.g., $100\text{A}$ at $3.3\text{V}$), diode dissipation reaches $40\text{W} - 70\text{W}$, capping conversion efficiency around $80-85\%$.
Our custom OEM power modules replace lossy diodes with low $R_{DS(on)}$ active N-Channel MOSFETs driven by synchronous timing controllers. By operating in the ohmic channel region, conduction loss obeys $P = I^2 \times R_{DS(on)}$. With channel resistance down to $1.2\text{m}\Omega$, power loss drops below $12\text{W}$, driving module efficiency up to 96.5%.
High input voltage variation (e.g., $18\text{V}-75\text{V}$ telecom/rail ranges) typically forces duty cycle degradation and severe capacitive switching losses in single-stage converters. Our engineering design implements a isolated two-stage topology:
This decoupling eliminates hard switching, suppresses dv/dt noise spikes, and optimizes planar transformer design for maximum power density ($>250\text{W/in}^3$).
Sealed industrial equipment operating in Spanish high-ambient temperature regions (such as Andalusia or Extremadura) cannot use forced-air fan cooling due to dust, humidity, or airborne salts. Our modules feature complete epoxy pot encapsulation enclosed in aluminum baseplates.
Internal heat generation is directly routed from high-power MOSFET junctions through thermally conductive dielectric substrates to the baseplate. This delivers a ultra-low thermal resistance ($\theta_{JC} < 1.2^\circ\text{C/W}$), permitting continuous 100% full-load operation up to $+100^\circ\text{C}$ baseplate temperature without active derating.

Technical Application: Naval surface combatants, submarines, and commercial offshore support vessels require robust AC-DC and DC-DC conversion compliant with MIL-STD-1399 (Section 300B) for voltage transients and harmonic distortion, alongside strict MIL-STD-461 electromagnetic compatibility.
Our OEM Anti-Salt, Anti-Mold, Anti-Corrosion IP68 UPS and high-density power modules undergo full conformal coating and hermetic baseplate sealing. They withstand high ambient humidity, salt spray fog, and high-impact mechanical shock (MIL-STD-810G vibration resistance) critical for naval operations.
Regional Focus: Industrial Hubs in Catalonia (Barcelona), Automotive Manufacturing Belt in Valencia and Zaragoza.
Technical Application: Automated guided vehicles (AGVs), robotic arm motor controllers, and automated sorting centers depend on isolated DC-DC bus converters that convert high battery voltage ($48\text{V}-96\text{V}$) to lower regulated logic levels ($5\text{V}, 12\text{V}, 24\text{V}$) with minimal noise ripple.
By implementing synchronous rectification, our half-brick and quarter-brick converters reduce electromagnetic radiated emissions (EMC), clearing CISPR 32 / EN 55032 Class B limits with minimal external EMI filtering component counts on the main system board.
Understanding the regulatory mandates, sustainability targets, and supply chain standards shaping procurement decisions for Spanish OEMs.
Spain’s updated Integrated National Energy and Climate Plan (PNIEC) mandates a 81% share of renewable electricity by 2030. This drives an immediate transition from centralized power plants to decentralized microgrids.
Power converter efficiency is now a regulatory bottleneck. Replacing legacy 85% efficient converters with 96% synchronous rectifier modules reduces total parasitic thermal dissipation across renewable substations by hundreds of megawatt-hours annually.
Navigating Spanish import protocols requires strict adherence to European Union directives. All custom OEM modules exported to Spain comply with CE marking, low voltage directive (LVD 2014/35/EU), and EMC directive (2014/30/EU).
For medical diagnostic equipment deployed across Spain’s SERMAS healthcare network, our supplies satisfy UNE-EN 60601-1 ed. 4.0 isolation requirements, offering 2×MOPP protection and low leakage current profiles.

We offer customized mechanical footprints (Full Brick, Half Brick, Quarter Brick, Eighth Brick, and 1/16th Brick) with bespoke pinout configurations, custom baseplate mounting holes, and specialized cold-plate interface geometries tailored to your mechanical chassis constraints.
Achieving system-level compliance against MIL-STD-461, DO-160, or EN 55032 can lead to unpredictable test delays. We engineer matched converter-plus-filter chains. Our active 3-phase Power Factor Correction (PFC) modules deliver low harmonic distortion (THD < 3%) and unity power factor (> 0.99) directly out of the box.
Every industrial module exported to Spain undergoes strict quality verification, including thermal shock cycling ($-55^\circ\text{C}$ to $+125^\circ\text{C}$), full-load burn-in at elevated temperatures, dynamic transient load testing, and 100% dielectric isolation testing (up to 4250 Vdc isolation) prior to shipment.
Addressing key queries regarding international shipping, custom OEM NRE costs, compliance certifications, and technical integration protocols.
In high ambient regions of Spain, semiconductor junction temperature ($T_j$) is the primary driver of failure according to Arrhenius thermal acceleration models. For every 10°C drop in operating junction temperature, component lifespan approximately doubles. By replacing lossy Schottky diodes with high-efficiency synchronous MOSFETs, internal power dissipation drops by 60% to 80%. This keeps internal component junction temperatures significantly cooler under identical ambient baseplate conditions, boosting module Mean Time Between Failures (MTBF) past 2.5 million hours (MIL-HDBK-217F).
We provide extensive OEM customizations for rail equipment manufacturers in Spain, including custom input voltage mapping (addressing continuous 24V, 48V, 72V, 96V, and 110V nominal inputs with EN 50155 surge capability up to 154V), tailored PCB pin layouts, conformal coating against condensation, integrated active hold-up logic for Class S2 brownout compliance (10ms to 20ms full-load hold-up), and custom aluminum baseplate cold-plate geometry for direct chassis heat sinking.
Standard prototype samples of catalog DC-DC converters and active PFC modules are dispatched within 1 to 2 weeks. Custom OEM production runs typically carry a lead time of 6 to 8 weeks following technical design freeze. We support Incoterms including DAP, DDP, and CPT to major Spanish industrial centers (Barcelona, Bilbao, Madrid, Valencia, Seville), handling export documentation, CE compliance declaration records, and customs clearance procedures seamlessly.
Line voltage phase imbalance is common on naval vessels (such as Navantia shipboard grids) and remote renewable microgrids in rural Spain. Our 3-phase MPFIC active PFC front-end modules utilize independent per-phase active current tracking loops. Even under severe phase-to-phase voltage asymmetry (up to 15% imbalance), the module maintains a unity power factor (> 0.99) and low total harmonic distortion (THD < 3%), preventing upstream transformer overheating and line filter saturation.
