OEM/ODM Custom Converter Factory & Suppliers for the Spain Market

Industry Whitepaper: Electrification Dynamics & OEM Sourcing in Spain

Spain stands as the second-largest automotive manufacturer in Europe and a primary production hub for commercial vans, urban transit buses, agricultural utility vehicles, and industrial logistics equipment. As the Kingdom accelerates its transition toward zero-emission transportation—underpinned by the Strategic Project for Economic Recovery and Transformation of the Electric and Connected Vehicle (PERTE VEC) and the National Integrated Energy and Climate Plan (PNIEC 2023–2030)—tier-1 integrators and vehicle OEMs require highly robust, OEM/ODM custom power conversion solutions.

Manufacturing power electronic components for Spanish automotive hubs—such as Valencia, Catalonia, Aragon, Castile and León, and Galicia—demands a comprehensive understanding of both operational environments and European regulatory frameworks. Power modules, On-Board Chargers (OBC), and DC-DC converters must endure distinct geographical challenges, from the high ambient temperatures of Andalusia (frequently exceeding 40°C in summer) to the saline atmospheric conditions along the Iberian coastline.

Technical Standards & Quality Mandates for Spanish Integrators

Sourcing power electronics from an overseas OEM/ODM supplier requires absolute adherence to strict compliance protocols. Products destined for deployment across Spain's autonomous communities must fulfill severe electromagnetic compatibility (EMC) and functional safety demands:

• UNECE Regulation 10 (R10 Rev. 6): Essential for electromagnetic interference immunity and emission compliance across European automotive electrical sub-assemblies.
• UNECE Regulation 100 (R100): Strict safety standards covering high-voltage electrical safety, insulation resistance, and thermal runaway prevention in electric drivetrains.
• CE & Low Voltage Directive (LVD 2014/35/EU): Mandatory marking for all industrial AC-DC chargers and stationary power equipment distributed within the European Union.
• ISO 15118 & DIN 70121: Protocol stacks enabling Smart Charging, automated handshake, and Vehicle-to-Grid (V2G) / Vehicle-to-Load (V2L) bidirectional energy exchange.

Localized Application Scenarios in the Spanish Ecosystem

Custom OEM/ODM converters and chargers engineered by our facilities are designed to directly serve the most demanding sector-specific applications across Spain's industrial landscape:

Factory Engineering Supremacy: Custom OEM/ODM Platform Architecture

As an industry-leading power converter designer and manufacturer, our engineering capabilities span board-mounted isolated DC-DC bricks, non-isolated Point-of-Load (POL) modules, and heavy-duty e-Mobility power conversion platforms. We provide Spanish OEMs with complete freedom over mechanical dimensions, electrical parameters, cooling interfaces, and firmware communication stacks.

Advanced Silicon Carbide (SiC) & GaN Topologies

By leveraging third-generation wide-bandgap semiconductors—specifically Silicon Carbide (SiC) MOSFETs and Gallium Nitride (GaN) power switches—our custom converter designs achieve switching frequencies significantly higher than traditional silicon-based architectures. This yields dramatic reductions in magnetic component volume and thermal dissipation losses, granting peak efficiency ratings up to 96% and industry-leading power density.

For Spanish vehicle designers targeting lightweighting goals under PERTE VEC subsidies, our compact 2-in-1 and 3-in-1 integrated OBC platforms save valuable chassis volume while eliminating external inter-module cabling.

Wide Voltage Spectrum & Standardized Brick Footprints

Our OEM/ODM manufacturing facilities produce standard and customized isolated DC-DC converters spanning micro-power footprints up to full-brick packages (1/32nd, 1/16th, 1/8th, quarter, half, and full brick). Standard input voltage windows are meticulously tuned for industrial, railway, telecom, and automotive power buses:

• Low & Intermediate Bus Inputs: 9–36V, 9–75V, 18–36V, 18–75V, and 36–75V DC for 12V/24V/48V battery systems and telecommunication equipment.
• High-Voltage & Transportation Lines: 16–160V, 34–160V, and 66–160V DC compliant with EN 50155 railway rolling stock requirements.
• E-Mobility High-Voltage Drivetrains: 180–400V, 300–500V, and 400–650V DC optimized for modern EV lithium-ion battery architectures (LiFePO4 and NCM).
• Non-Isolated POL Regulators: 2.5V to 60V input ranges adhering strictly to DOSA (Distributed-power Open Standards Alliance) pinouts for localized FPGA, DSP, and processor power rails.

Ruggedized Thermal Management & Environmental Sealing

Operating machinery in Iberian agricultural fields or coastal transport hubs requires unyielding protection against particulate matter, high humidity, and mechanical impact. Our custom OEM/ODM converters utilize structural aluminum die-cast enclosures filled with thermal conductive potting compounds (UL 94V-0 rated). Flexible cooling options include:

• Conduction Cooling: Baseplate-cooled designs transferring heat directly to the vehicle chassis or cold plate.
• Forced Air Cooling: Smart PWM-controlled, dual-ball bearing fan assemblies optimized for airflow across heat sink fins.
• Liquid Cooling Interfaces: Precision water/glycol channels designed to integrate seamlessly into the main vehicle thermal loop.

Strategic Development Trends in Spain's Power Market (2025–2030)

The Spanish power electronics sector is experiencing a rapid technological shift driven by national decarbonization goals, fleet electrification mandates, and industrial automation. OEM engineering teams must align their multi-year product roadmaps with several key technological trends:

1. Expansion of Bidirectional V2X Infrastructure

With Spanish municipal grids and renewable energy operators integrating decentralized storage, bidirectional charging (V2L - Vehicle to Load, V2G - Vehicle to Grid) is becoming a standard requirement for light commercial fleets and municipal vehicles. Our 3.3kW bidirectional OBC modules allow vehicles to operate as mobile power banks, delivering 230V AC pure sine wave power directly to job sites or backfeeding electricity into the local grid during peak price intervals.

2. Transition from Standalone Modules to Integrated Powertrain Assemblies

To reduce bill-of-materials (BOM) complexity and assembly time on Spanish production lines, OEMs are abandoning standalone chargers and separate DC-DC units. The industry standard has shifted decisively toward 2-in-1 (OBC + DCDC) and 3-in-1 (OBC + DCDC + PDU) integrated power distribution centers. Our OEM factory customizes interior layout, high-voltage connector orientation (Amphenol, TE Connectivity, or Rosenberger), and mounting hole dimensions to match exact vehicle chassis geometries.

3. ISO 15118-20 Plug & Charge Capability

Seamless charging without manual card authentication is rapidly expanding across Spanish public charging networks (such as Iberdrola BP Pulse, Endesa X Way, and EDP). Our OEM charger firmware stacks support ISO 15118-20, enabling automated encrypted communication between the vehicle and charging pile, dynamic load control, and smart grid optimization.
