SiC & GaN switches
Wide-bandgap devices switch faster with lower loss than silicon, raising frequency and slashing conduction losses in the power path.
The platform
Power density is a systems problem. We engineer the whole system.
Switches, magnetics, topology, control, and thermal management are designed together — not bolted on. That integration is what lets our converters be small, efficient, and quiet all at once.
How it fits together
One co-designed conversion stack
Every Powder Devices converter is built from five tightly-coupled layers. Optimizing any one in isolation leaves performance on the table; optimizing them together is our core competency.
- Wide-bandgap switches set the frequency ceiling.
- Resonant topology makes that frequency lossless.
- Powder-core magnetics turn frequency into smaller volume.
- Digital control & thermal design keep it safe and reliable.
Core technologies
What's inside every converter
CLLC resonant topology
Zero-voltage switching across the load range cuts switching loss and EMI, and enables clean bidirectional power flow.
Powder-core magnetics
Distributed-gap powder cores saturate softly and run cool, while planar windings give repeatable, manufacturable inductance.
Digital control
A real-time controller closes the loop, runs diagnostics, and exposes setpoints and telemetry over CAN-FD.
Thermal management
Cold-plate-integrated power modules and optimized spreaders move heat to coolant rated up to 65 °C inlet.
Manufacturing & test
Automated assembly with 100% end-of-line functional, efficiency, and high-voltage isolation screening and traceability.
Switches & topology
Fast switches, lossless transitions
Silicon-carbide and gallium-nitride devices let us switch at hundreds of kilohertz. On their own, that would mean high switching loss. The CLLC resonant tank solves it: devices turn on at zero volts and turn off at near-zero current, so the speed buys density without the thermal penalty.
The same resonant structure is naturally symmetric, which is what makes our HVX™ converters cleanly bidirectional — the controller simply reverses the roles of the primary and secondary bridges.
Magnetics — our namesake
Why "Powder" Devices
Conventional ferrite cores saturate hard and lose efficiency under transient load. Distributed-gap powder cores — iron-based powders bound in an insulating matrix — store energy throughout the core volume, saturate gracefully, and tolerate DC bias far better.
We pair them with planar, PCB-integrated windings for tightly controlled leakage inductance, excellent thermal coupling, and the repeatability that high-volume automotive production demands. The result is the dense, low-EMI magnetics at the heart of every converter we ship.
