Where MVGS earns its place
Built for the gap between lab equipment and utility-scale power.
MVGS is most useful when the DUT sits at medium voltage and the test team needs programmable grid behaviour, regenerative loading and project evidence in the same bench plan.

Medium-Voltage Grid Simulation for AI Data Center Power and MW-Scale Power Electronics
The MVGS Series is a medium-voltage grid simulator for projects that need direct 5 kV to 35 kV output, 1 MVA to 20 MVA+ capacity, four-quadrant regenerative operation and programmable grid disturbances in one laboratory platform. It is positioned for AI data center solid-state transformers, energy-storage PCS, high-power renewable-energy systems, and megawatt-scale power-electronics validation.
MVGS is not an AI model or AI software product. It is power-infrastructure validation equipment for teams moving high-power facilities toward medium-voltage distribution, SST conversion stages, energy-storage PCS validation, and grid-interactive renewable-energy systems.
Engineering Use Cases
Typical MVGS projects include AI data center SST validation, SST converter-stage testing, energy-storage PCS source/load validation, renewable-energy inverter and PCS ride-through testing, harmonic and inter-harmonic immunity work, and regenerative laboratory grid emulation. The common thread is that the device under test needs a real medium-voltage electrical boundary rather than a low-voltage approximation.
Validation Workflow
MVGS can support grid-code-oriented workflows such as IEEE 1547, UL 1741, IEC 62116, IEEE 519, and GB/T 19964 test contexts, subject to final configuration and test-plan review. Standard capabilities include LVRT, HVRT, ZVRT, sag, swell, harmonic injection, unbalance simulation, independent three-phase control and programmable RoCoF.
Configuration and RFQ Notes
The modular Power Cell Cascaded topology allows configurable direct medium-voltage output, reducing the need for large external step-up transformers in suitable laboratory setups. Standard control interfaces include LAN, RS485 / Modbus RTU and a fiber optic sync interface; optional analog I/O and RS232 depend on the released configuration.
For quotation, provide the voltage class, MVA rating, input voltage, output mode, cooling preference, LVRT/HVRT/ZVRT profiles, harmonic order, RoCoF requirement, expected DUT type, site power constraints, protection needs, interface requirements and target acceptance evidence. MVGS is usually not the right starting point for low-voltage benchtop AC source work or projects without a defined safety boundary, cooling plan and FAT/SAT method.

Use MVGS when the project has a real medium-voltage boundary.
Strong fit
- AI data center MV power architecture validation
- SST, MV UPS, PCS and wind-converter test benches
- Projects needing direct MV output instead of a step-up transformer chain
- RFQs that require FAT/SAT records, waveform evidence and configuration traceability
Review alternatives
- Low-voltage benchtop AC source work
- Small inverter tests where MV site power is not available
- Projects without a defined safety boundary, cooling plan or acceptance method
- Teams looking for AI software rather than power-infrastructure validation hardware
