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

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.
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.
Why IGBT? The Case for Active Front End Power Conversion
Our AFE+Chopper IGBT architecture delivers measurable advantages over traditional thyristor-based converters, especially for modern MW-scale hydrogen plants connected to variable grids.
- Power Factor
- >0.99 with active control, no passive filter needed
- DC Bus Response
- Fast, ~500 Hz bandwidth
- Transformer Cost
- ~40% lower, uses a single-winding distribution transformer
- Grid Compatibility
- Excellent, IEEE 519 compliant out of the box
Thyristor converters remain a proven, robust choice for stable baseload applications. Yonder offers both architectures and recommends the right fit for your project's grid profile and operational requirements.

What integrators ask us before shortlisting.
All major types, Alkaline, PEM, AEM, and SOEC. We engineer the power conversion output to match your specific electrolyser manufacturer's sensitivity envelope.
Yes. Our IGBT architecture is designed for rapid response to volatile grid inputs, including renewable sources with fluctuating output.
As early as possible, ideally at plant specification stage. The earlier we co-engineer the electrical architecture, the lower your integration risk at commissioning.
No. Yonder's scope is power electronics only, the DC power conversion architecture between the grid and your electrolyser. We do not supply storage, transport, or the electrolyser itself.
Every system includes an 18-month warranty covering field service, spare parts, and remote performance monitoring. Extended maintenance contracts are available for ongoing coverage beyond the warranty period.
Our power conversion architecture supports any precision DC application at scale, green ammonia, green steel, refineries, chemicals, and other process electrification projects.
Next Step
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.
