Engineered for high-frequency switching test setups, Hardware-in-the-Loop (HIL) BMS validation, and aggressive dV/dt transient testing in wide-bandgap (SiC/GaN) converter R&D laboratories across Serbia.
Understanding the critical electromagnetic, dynamic, and thermal demands imposed by Silicon Carbide (SiC) and Gallium Nitride (GaN) switching devices on programmable DC power architectures.
Wide-bandgap semiconductors operate at switching speeds up to 10 times faster than legacy silicon IGBTs, exhibiting extreme dV/dt rates exceeding 50 to 100 V/ns. Under Double Pulse Test (DPT) conditions, the programmable DC power supply providing the high-voltage bus must withstand massive inductive kickback and fast-transient current spikes without tripping over-voltage protections or introducing low-frequency ringing that distorts switching energy ($E_{on}$ and $E_{off}$) calculations.
Our power supplies feature an ultra-low output capacitance filter option combined with current-fed power processing topologies. This guarantees high DC bus stiffness while effectively decoupling line-side noise from the device under test (DUT).
Traditional voltage-fed programmable supplies rely heavily on massive output electrolytic capacitor banks to maintain voltage stability. However, when applied to dynamic SiC/GaN converter testing, these large capacitors store destructive energy that can vaporize power switches during an shoot-through fault or gate breakdown event.
Our proprietary current-fed topology utilizes an inductor as the primary energy storage element on the DC bus. In the event of a SiC MOSFET breakdown during test, the current-fed topology inherently limits short-circuit current, preserving the device sample for failure mode analysis (FMA) and safeguarding sensitive laboratory measuring equipment.
Key Takeaway for Power Electronics Test Engineers in Serbia: Characterizing modern SiC/GaN traction inverters, solar microinverters, and high-frequency DC-DC converters requires a DC power supply that balances extreme voltage regulation ($<0.05\%$) with fast transient recovery ($<100\mu s$) and current-fed safety architecture.
| Performance Metric | Standard Voltage-Fed Supplies | Magna-Power Current-Fed Systems | Impact on SiC / GaN Test Integrity |
|---|---|---|---|
| Short-Circuit Fault Energy | High (Destructive Cap Discharge) | Controlled (Inductive Limit) | Prevents complete chip destruction during gate breakdown |
| Transient Recovery (10-90% Load Step) | > 2 ms to 5 ms | < 100 µs (High Slew Option) | Maintains bus voltage stability during high-burst pulse testing |
| Output Noise & Ripple | 50 mV – 150 mV RMS | < 3 mV RMS (Low Ripple Option) | Eliminates baseline noise for precise double pulse switching loss integration |
| Regenerative Energy Handling | Requires external blocking diodes | Integrated blocking option available | Protects supply from back-EMF generated by inductive loads |
Supporting Serbia’s rapid evolution into a Southeastern European center for automotive component manufacturing, electric mobility engineering, and renewable energy innovation.
With major automotive production investments expanding in Kragujevac (MIND Park ecosystem) and electronic assembly clusters in Niš, our multi-channel battery cell simulators (e.g., 24-Channel BMS Simulator) provide crucial Hardware-in-the-Loop (HIL) testing capability. Engineers simulate precise cell-level voltages, temperature coefficients, and active balancing algorithms for modern electric vehicle (EV) Battery Management Systems.
Aligned with the Science Technology Park Novi Sad and regional solar PV plant expansion, our high-power MagnaDC supplies pair with Photovoltaic Power Profile Emulation (PPPE) software. This enables Serbian power engineering teams to simulate real-world solar array non-linear I-V curves, microgrid transient drops, and maximum power point tracking (MPPT) performance under variable irradiance conditions.
Top engineering faculties such as the School of Electrical Engineering at the University of Belgrade rely on high-precision coin cell and bipolar battery simulators (such as the Rohde & Schwarz NGM series) for cutting-edge electrochemical research, low-power IoT energy harvesting characterization, and wide-bandgap SiC power converter topology prototyping.
Serbia is positioned as a primary growth node in the Western Balkans. Key structural trends are accelerating the need for high-end programmable power hardware.
Serbia’s strategic position, free trade agreements, and skilled workforce have attracted leading Tier-1 and Tier-2 automotive suppliers. Manufacturing facilities producing traction controllers, on-board chargers (OBC), and DC-DC converters require reliable, scalable test power supplies with standardized SCPI and Ethernet/LXI interfaces for continuous 24/7 automated line testing (ATE).
Under the Green Agenda for the Western Balkans, Serbia is rapidly increasing its share of wind and solar grid integration. Testing the compliance of grid-tied inverters against European EN 50549 standards requires robust programmable power sources capable of sourcing up to megawatt-level power while tolerating grid fault conditions.
Fully vertically integrated manufacturing ensures unparalleled product longevity, rapid spare parts availability, and strict adherence to international quality standards.
From sheet metal fabrication and magnetic transformer winding to surface-mount PCB assembly and final full-power burn-in, every step is performed in-house. This minimizes supply chain disruptions and ensures strict quality control.
Whether operating a 1.5 kW 1U rack-mount SLx unit or a 1 MW ML Series water-cooled cabinet, the SCPI command structure, LabVIEW drivers, and MagnaCTRL management software remain 100% identical. Upgrade your test bench without rewriting code.
Supported by extensive European service infrastructure, Serbian customers receive prompt technical consultation, field recalibration support, and comprehensive long-term spare parts availability.
