Serving the Mechatronics Capital: Brainport Eindhoven
The Brainport Eindhoven ecosystem represents Europe’s foremost high-tech powerhouse. Anchored by world-leading semiconductor lithography engineering, advanced optical assembly, automated precision manufacturing, and next-generation electric mobility, Eindhoven operates under strict physical and thermal power budgets. Subsystems integrated into lithography support gear, automated material handling (AMH) cleanroom AGVs, and precision robotics require auxiliary power architectures that ensure absolute noise immunity, galvanic isolation, and zero common-mode transient coupling.
As high-voltage DC architectures migrate from 48V telecommunication buses toward 400V, 600V, and 800V DC intermediate buses in mobile robotics, test benches, and heavy-duty electric commercial drivetrains across North Brabant, procurement teams need reliable export partners who deliver verified, high-MTBF power topologies. Shenzhen Eltrum Electronic bridges this demand, manufacturing ruggedized step-down buck, step-up boost, bidirectional buck-boost, and transformer-isolated power systems tailored for European integration.
Eindhoven High-Tech Requirements vs. Eltrum Topologies
How our high voltage power converters map into Dutch high-tech system specifications:
- Low Ripple & Phase Jitter: Advanced LC multi-stage filtering suppresses output ripple below 30mVp-p, protecting optical encoders, interferometer lasers, and sensitive sensory clusters.
- 1500V – 3000V Galvanic Isolation: Transformer barriers eliminate ground loops between high-power motor drivers and micro-controller signaling logic.
- Thermal Densification: Fully encapsulated aluminum housings achieve thermal transfer exceeding 2.0 W/m·K, operating under passive conduction within sealed cleanroom modules.
- Harmonic & EMC Mitigation: Designed in compliance with CISPR 32 / EN 55032 Class B emission thresholds without external ferrite bulk.
Engineering Principles of High Voltage DC-DC Conversion
Choosing the right power converter topology prevents costly field failures, unexpected voltage sags under motor inrush, and thermal saturation in closed-cabinet industrial installations.
Galvanically Isolated Topologies
Utilizing high-frequency planar transformers and primary-to-secondary optocoupler feedback loops, our isolated converters decouple load grounding entirely from source floating potentials. Essential for 48V-72V industrial material handling equipment, medical diagnostics, and telecom distribution panels across Eindhoven where ground-fault safety and noise isolation are mandatory.
Four-Switch Synchronous Buck-Boost
When source voltages dynamically cross target levels—such as during high-capacity traction battery discharge cycles (dropping from 58.4V down to 38V) or wide-swing DC microgrids—our non-inverting synchronous buck-boost modules maintain steady, locked regulation. Integrated high-side MOSFET drivers guarantee rapid transient response times below 200 microseconds.
Synchronous Step-Down (Buck) Conversion
Where input voltage remains consistently higher than load voltage—such as dropping 72V, 48V, or 24V buses down to 12V, 5V, or 3.3V logic rails—our buck converters replace legacy diodes with low RDS(on) silicon carbide and silicon MOSFETs. This delivers efficiencies up to 96.8%, minimizing wasted heat inside tightly enclosed enclosures.

How our high-voltage DC-DC converters and battery chargers power systems across the Brainport Industries Campus (BIC), Automotive Campus Helmond, and North Brabant industrial clusters.
Cleanroom Logistics & AGVs

Compatible with: Lithography Aux RacksBESS & Industrial Microgrids
To bypass regional grid congestion (netcongestie) in Noord-Brabant, local manufacturing facilities deploy local battery energy storage systems (BESS). Our 1500W RS485-controlled buck-boost stabilizers regulate varying DC bus voltages into steady feeds.
Standard: Dutch Solar PV & BESSNavigating Net Congestion, 800V Transitions & EU Norms
The province of Noord-Brabant faces severe electrical grid congestion (netcongestie), forcing manufacturing sites and logistics operators in Eindhoven to install autonomous DC microgrids, peak-shaving containerized batteries, and rooftop PV infrastructure. This decentralization creates high demand for rugged DC-DC power electronics capable of handling fluctuating voltage swings while maintaining conversion efficiencies above 95% to reduce heat dissipation in enclosed spaces.
At the same time, the transition from 400V toward 800V DC architectures in commercial vehicles and heavy automated handling systems requires power converters with enhanced dielectric creepage and clearance distances, higher impulse withstand ratings, and wide-bandgap silicon carbide (SiC) switching devices.
