Wolfspeed's New System Reference Designs

Categories // Latest News Power

Wolfspeed has introduced three new reference designs that can be used for simulations or as drop-in design solutions.

BUCK BOOST EVALUATION KIT:

The KIT-CRD-3DD12P buck-boost evaluation kit is optimized to demonstrate the high-speed switching capability of Wolfspeed’s discrete MOSFETs and diodes. Designers can quickly evaluate the performance of 4-lead and 3-lead TO-247 package MOSFETs, as well as diodes in TO-247 and TO-220 packages. The kit contains everything needed including a heatsink, thermal interface, inductor, and other hardware as well as two Wolfspeed C3M MOSFETs to allow the user to begin testing within minutes of unpackaging the kit.

Features:

  • Includes footprints for both 3 and 4-lead TO-247 packages allowing for easy comparison
  • Includes SMA connectors for capturing clean VGS waveforms
  • MOSFET and diode footprints included in both top and bottom positions
  • No additional capacitors needed to run in boost or buck converter topologies

Supported Topologies:

  • Synchronous boost converter
  • Synchronous buck converter
  • Non-synchronous boost converter
  • Non-synchronous buck converter
  • Half-bridge
  • Full bridge (requires 2 kits)

6.6 KW BI-DIRECTIONAL ON-BOARD CHARGER FEATURING 30% HIGHER POWER DENSITY

The new 6.6 kW Bi-Directional On-Board Charger targets high-power-density, high-efficiency on-board charger applications and features Wolfspeed’s new 650V C3M SiC MOSFETs in a TO-247 package. The system delivers 54W/in3 power density and exceeding 96.5% in peak efficiency with 67kHz switching frequency for CCM totem pole PFC and 150kHz-300kHz for a CLLC resonant converter.

Features:

  • High power density
  • High efficiency
  • Bi-directional power flow capability
  • Cost-effective drop-in solution

Supported Topologies:

  • Bi-directional electric vehicle battery chargers
  • Grid-tied distributed generation
  • Energy storage systems

300 KW THREE-PHASE INVERTER FEATURING THE NEW XM3 HALF-BRIDGE POWER MODULE

The 300 kW three-phase inverter demonstrates system-level power density and efficiency obtained by using Wolfspeed’s new XM3 module platform. The XM3 is optimized for SiC MOSFETs in a high-density, low-inductance footprint, which can reduce system losses and simplify overall design for low-loss, high-frequency operation. The three-phase inverter has >2x the power density of comparable Si based designs and >98% efficiency.

Includes:

  • CAB450M12XM3: 1200 V, 450 A Half-Bridge XM3 Modules
  • CGD12HBXMP: XM3 Evaluation Gate Driver
  • Optimized laminated bussing for reduced power Loop inductance
  • Dc-link capacitors
  • Sensors and control hardware

Applications:

  • Motor and traction drives
  • Grid-tied distributed generation
  • High-efficiency converters
