Most power conversion issues don't show up until commissioning. By then, they're costly and difficult to reverse.
You're integrating a first-of-kind hydrogen plant. Your electrolyser OEM has strict DC power requirements. Your grid connection has its own volatility profile. And your project financiers have a go-live date that doesn't move.
Generic converters are built for shelf availability, not your sensitivity envelope. When they clash with real-world grid conditions and electrolyser specs, the result is retrofit costs, schedule overruns, and a project that misses its hydrogen production targets.
You need a power partner who starts with your spec, before manufacturing begins.
Precision DC power conversion for your electrolyser.
Green hydrogen projects involve a layered supply chain. Yonder's role is precise: we deliver the DC power conversion architecture that sits between the grid and the electrolyser. Understanding exactly where we contribute (and where we don't) matters to how you plan your project.
Secures offtake, sets the commercial timeline.
Defines the strict DC power requirements and the electrochemical sensitivity envelope.
Yonder supplies the DC power conversion equipment to the electrolyser manufacturer or EPC contractor, engineered to the electrolyser's exact requirements.
Every system is engineered to your electrolyser.
Send your electrolyser manufacturer, chemistry, MW project scale, and grid parameters. Our engineers return a preliminary converter configuration with a quick turnaround.
Unlike off-the-shelf vendors, Yonder enters at the plant specification stage. Integration issues are engineered out before a single component is manufactured.
On-site integration directly with your electrolyser and grid tie-ins. We don't hand over a document. We stay until the plant runs.
Every system ships with an 18-month warranty, field service, and spare parts support. Extended maintenance contracts are available for ongoing coverage.
Built for every electrolyser chemistry. Engineered for your project.
Yonder's Power Core delivers precision DC output matched exactly to your electrolyser's sensitivity envelope, whether you're running Alkaline, PEM, AEM, or SOEC.
Grid to electrolyser: the converter chain

Grid interface and isolation. Oil or dry (VPI) configurations up to 25 MVA, with 2–27 windings and custom vector groups.

Proven robustness for high-current, stable baseload applications. Highly serviceable, cost-effective for predictable power demand profiles.

Most specified for modern MW-scale projects. High power factor, exceptionally low harmonic distortion, rapid response to grid variability.

Next-generation switching efficiency in an ultra-compact footprint. Deployed on cutting-edge AEM platforms in Europe.
Every topology ships as modular, integrated, or ruggedised.
Indoor/outdoor scalable converter cabinets for integration into existing plant infrastructure.
Fully integrated, pre-tested at our Pune facility to reduce on-site civil works and delays.
Ruggedised enclosures for harsh, remote, or extreme weather deployments.
Delivered. Commissioned. Running.
Power conversion systems engineered and commissioned across India and the EU.

SiC-based AC-DC converter for advanced AEM electrolyser integration.

1.2 MW systems built on an AFE + DC/DC architecture for commercial-scale production.

5.7 MW thyristor-based DC power for a green hydrogen electrolyser plant.
We've solved hard electrical problems in extreme environments since 1972.
Talk to our engineersYonder is the DC power conversion division of the Ador Group, 118 years of Indian industrial engineering heritage. Our Ador Powertron team has built high-power custom equipment for defence systems since 1972, where failure is not an option.
We brought that same discipline to green hydrogen. Today we're one of the only fully Indian-owned companies delivering MW-scale H₂ power conversion, completely indigenously designed and manufactured.
Why integrators choose Yonder
Design, engineering, manufacturing, testing and QA happen entirely within our 118-year-backed Pune facility.
Our Ador Powertron heritage in high-reliability defence applications shapes how we approach industrial power conversion. Zero tolerance for field failure.
When your team requires verified domestic engineering and manufacturing, we're positioned to meet that requirement.
Built for hydrogen. Ready for the broader decarbonization stack.
Our power conversion architecture is electrolyser-agnostic and process-agnostic. If your industrial process requires precision DC power at scale, we can engineer it.

What integrators ask us before shortlisting.
How early in a project should we bring Yonder in?
As early as the electrolyser specification stage. That's when we can co-engineer the DC architecture to your OEM's sensitivity envelope and avoid retrofit costs at commissioning.
Which electrolyser chemistries do you support?
Alkaline, PEM, AEM and SOEC. Our converter architectures are chemistry-agnostic and tuned to each OEM's specification.
Where do you manufacture?
Design, engineering, manufacturing, testing and QA all happen at our Pune facility in India, backed by 118 years of Ador Group heritage.
What warranty and service is included?
Every system ships with an 18-month warranty, field service and spare parts support. Extended maintenance contracts are available.
Your commissioning date is fixed. Let's make sure your power conversion is too.
Share your electrolyser manufacturer, project scale, and grid parameters. Yonder engineers will review and respond with a preliminary converter configuration.
