Engineered for high current capability, ultra-low ripple, and IP67 resilience. From compact DIN-rail ready auxiliary converters to high-power industrial step-up units.
A comprehensive examination of synchronous rectification, EMI mitigation, thermal dissipation, and EU regulatory alignment for Central European systems integrators.
In conventional asynchronous boost converter circuits, the free-wheeling diode introduces continuous forward voltage drop ($V_F \approx 0.4\text{V} - 0.7\text{V}$), which creates severe thermal overhead in high-amperage industrial environments. In applications operating throughout industrial centers such as Budapest, Debrecen, and Győr, where high ambient heat can trigger thermal throttles inside enclosed sub-assemblies, conversion efficiency is non-negotiable. Our DC-DC boost converter lineup replaces the passive Schottky diode with an ultra-low $R_{DS(on)}$ N-channel MOSFET. This synchronous rectification topology limits $I^2R$ conduction losses, keeping operational efficiency consistently above 94% to 96.8% under continuous duty cycles.
Furthermore, critical switching frequencies are tuned between 100 kHz and 300 kHz, strikes an optimal balance between minimizing inductor core volume and suppressing transient switching spikes. With transient response times below 200 microseconds against a 50% step-load variation, our boost stages ensure that downstream programmable logic controllers (PLCs), high-torque servo drives, and telecommunications transceivers experience zero dropouts or logic resets.

Industrial machinery deployed across Eastern European transit corridors encounters wide seasonal temperatures ranging from sub-zero winter temperatures (-30°C) to scorching summer assembly line environments reaching +65°C internal ambient temperatures. Our converters utilize ADC12 aviation-grade extruded aluminum chassis integrated with deep-groove longitudinal heat sink fins. Thermally conductive silicone gel with a thermal conductivity coefficient exceeding 2.0 W/m·K is pressurized into the module enclosure, completely evacuating air pockets. This process provides dual protection: it functions as a mechanical damper mitigating vibrational harmonic stresses (tested to 5G acceleration loads under IEC 60068-2-6) while simultaneously sealing internal SMD arrays against particulate ingestion, moisture penetration, and galvanic corrosion.
Accelerating critical infrastructure projects across Hungary with engineered DC-DC voltage conversion modules.
With Debrecen and Göd emerging as European epicenters for lithium battery manufacturing and EV drivetrain engineering, our high-power boost modules step up 12V automotive battery banks to 24V and 48V auxiliary lines. They power on-board diagnostic sensors, industrial AGVs (Automated Guided Vehicles), and battery testing fixtures reliably.
Hungary’s agricultural plains (Alföld) feature extensive installations of ground-mounted solar farms and standalone irrigation systems. When solar string voltages sag during low-irradiance periods, our wide-input boost converters bridge low-voltage photovoltaic outputs up to stable 24V or 48V DC buses, ensuring telemetry nodes and remote actuators remain active.
For rural connectivity programs, emergency communications trailers, and railway signalling across MÁV corridors, our compact converters step 12V or 24V battery systems up to 30V/48V/57V DC. This provides uninterrupted power to Starlink dishes, microwave transceivers, and cellular base station repeaters with minimal electromagnetic interference.
