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.
Model Configuration
The series uses a configurable naming structure:
MVGS AAA-BBB-CCC-DDD-EEE
AAA: Rated output powerBBB: Rated output voltage line-to-lineCCC: Rated output currentDDD: OptionsEEE: Input voltage line-to-line
Available options:
-HV: Increased maximum output voltage for HVRT testing-W: Water cooling
Decide Whether MVGS Is the Right Commercial Path
MVGS is the commercial product page for projects that need a real medium-voltage programmable boundary: configurable 5 kV to 35 kV output, megawatt-scale apparent power, four-quadrant source/load operation, and defined disturbance workflows. It should not replace the grid-simulator selection guide, which owns vendor-neutral selection questions, or the medium-voltage grid-simulator RFQ guide, which owns procurement-document structure.
Use a lower-voltage or lower-power platform when the DUT connection, power envelope, event matrix, and facility boundary do not require MVGS. Review the broader power-supply and grid-simulator catalogue before treating medium voltage or MVA-scale capacity as a default requirement.
Evidence Required Before Configuration and Pricing
Send the DUT port voltage and current envelope, required MVA, power-flow directions, output mode, ride-through and disturbance profiles, grounding and protection boundary, cooling preference, facility one-line, interface requirements, and required FAT/SAT files. State which values are mandatory, which are targets, and which remain open for engineering review.
The MVGS selection guide is the released source for the published family specifications. For SST projects, also review the full-power SST test-bench boundary. Final ratings, event performance, protection, site regeneration, cooling, interfaces, and acceptance evidence remain configuration-specific.
Request an MVGS configuration review with the electrical envelope, facility constraints, and acceptance plan attached.
