Wide-bandgap core
Silicon-carbide and gallium-nitride power stages switch fast and run cool — shrinking magnetics while pushing efficiency past 97%.
Automotive-grade power electronics
High-voltage DC-DC, engineered for the 48-volt era.
Powder Devices builds isolated, bidirectional converters that bridge 800 V and 400 V battery systems to 48 V and 12 V domains — at the density, efficiency, and reliability modern electric platforms demand.

Why Powder Devices
A power-conversion platform, not just a part.
Every converter we ship is built on four engineering pillars — the same pillars that let us hit aggressive density, efficiency, and reliability targets without compromise.
Powder-core magnetics
Distributed-gap powder cores and planar windings — our namesake — deliver soft saturation, low EMI, and exceptional volumetric density.
Bidirectional & software-defined
Power flows both ways under CAN-FD control. Setpoints, droop, and energy-recovery behavior are all configurable in firmware.
Automotive-grade by design
Developed within AEC-Q, IATF 16949, and ISO 26262 workflows — from component selection to end-of-line test.
Product families
Three converter platforms. One system architecture.
From the high-voltage battery bus down to legacy 12 V loads, our converters share a common control, communication, and qualification foundation.

The platform
Density and efficiency, engineered together.
Our converters pair wide-bandgap switches with resonant CLLC topologies and proprietary powder-core magnetics. The result is soft-switched conversion that stays efficient across the entire load range — not just at a single rated point.
- Zero-voltage switching across 10–100% load keeps thermals and EMI low.
- Planar transformers deliver repeatable leakage inductance for tight production tolerances.
- Liquid-cooled cold-plate designs operate to 65 °C coolant inlet.
Applications

Quality & reliability
Qualified to perform where it matters.
Our hardware and processes are developed against the standards automotive programs depend on — and every unit is screened on a 100% end-of-line functional and HV-isolation test before it ships.

Components, processes, and designs are developed in accordance with the standards above. Qualification status varies by product and is documented in each datasheet, available under NDA.
How to engage
From first email to integration support.
We work directly with engineering teams. Because our detailed datasheets contain proprietary design information, full documentation is shared under a mutual NDA.
Request & scope
Email engineering@powderdevices.com with your architecture, power level, and timeline. We respond within two business days.
NDA & datasheet
We execute a mutual NDA, then share the full datasheet, application notes, and qualification summary for your target product.
Samples & support
Engineering samples and evaluation fixtures ship to your bench, backed by hands-on integration and applications support.
