1. INTRODUCTION
This user guide provides an overview of Wolfspeed’s CRD25DA12N-FMC 25 kW three-phase inverter reference
design including key system specifications, sub-system functional descriptions, performance test data, and
mechanical assembly. The CRD25DA12N-FMC design was developed to provide power electronics engineers
with a hardware evaluation platform and reference design files to support early design-in activities of the
Wolfspeed WolfPACK™ baseplate-less power module platform. In conjunction with this user guide, the
complete suite of reference design files including schematics, PCB layout, Gerber files, BOM, and 3D CAD files
are available for download from the CRD25DA12N-FMC landing page on Wolfspeed’s website.
The CRD25DA12N-FMC is a complete, easy-to-use, flexible power stage designed around the CCB021M12FM3
(1200 V / 21 mΩ) Wolfspeed WolfPACK™ six-pack power module. As demonstrated in the block diagram below,
this design intends to provide everything needed to quickly evaluate performance out of the box while also
providing the resources to expand its capabilities to suit target end-application needs. To this end, included on
this single-PCB solution is DC bus capacitance with low-inductance power planes, gate drivers, current and
voltage sensing, thermal management, and various control peripherals.
By default, the CRD25DA12N-FMC is designed to be evaluated as a simple three-phase inverter topology, but
the flexibility of the generic power stage makes it simple to adapt to other applications. As such, the design is
ideal for evaluating or scaling up to higher power levels in industrial motor drives, power supplies, and
renewable energy applications, or as the bi-directional active front end (AFE) stage for off-board electric vehicle
(EV) fast charging.
