Design embedded servo drives with Wolfspeed Silicon Carbide
Designing servo drives with Wolfspeed silicon carbide enables smaller, more efficient and power dense embedded servo drives. Silicon carbide can also overcome the thermal challenges that plague IGBTs, further reducing the size of drives and resulting in longer system life.
Optimize servo drive systems with Wolfspeed 650 V MOSFETs
Wolfspeed 650 V silicon carbide MOSFETs allow servo drive designers to optimize systems for maximum efficiency at a reduced size and cost. For example, in an 11 kW, 8 kHz system upgrading to a semi-bridgeless Totem Pole-PFC and replacing IGBTs in the inverter with drop-in silicon carbide MOSFETS yields:
- 2% efficiency improvement
- 220 W reduction in losses
Redesigning the PFC using a bridgeless totem pole topology and upgrading the inverter with silicon carbide MOSFETs improves efficiency even more to 2.4%.
When compared to high-speed, soft-switched IGBTs, Wolfspeed 650 V MOSFETs offer drastically lower conduction losses and almost no switching losses, significantly improving the performance of embedded industrial motor drives.
Reduce servo drive size while boosting efficiency at higher temperatures with Wolfspeed silicon carbide
Wolfspeed’s Six-Pack WolfPACK™ power modules enable superior performance and system efficiency. When compared to the best IGBT solutions in a 25 kW inverter system, the WolfPACK™ achieves 1.1% higher efficiency with a 77% smaller heat sink (0.31 L vs 1.37 L).
Conversely, the WolfPACK can run at higher loads with smaller heat sinks, allowing designers to design embedded drive systems that are smaller and lighter and require up to 77% smaller heat sinks. Even at a higher 16 kHz switching frequency with the same heat sink, silicon carbide remains thermally stable and outperforms silicon IGBTs, causing further downsizing of passives. The smaller, lighter servo drives cause fewer complications when integrating the servo motor as often seen in industrial automation.
Quickly evaluate your designs with the NEW 25 kW FM3 Three-Phase Inverter
Designed to target industrial motor drives, Wolfspeed’s new 25 kW FM3 Three-Phase Inverter reference design provides comprehensive support to early SiC design-in activities. CRD25DA12N-FMC enables quick performance evaluation out of the box as a simple three-phase inverter topology. The flexibility of the generic power stage makes it simple to adapt to other applications, making it an ideal solution to evaluate or scale up power levels in industrial motor drives. This design features Wolfspeed’s 21 mW six-pack WolfPACK™ module with pre-applied TIM and achieves peak efficiencies over 99.5%, power density of 5.7 kW/L, and 30 Arms capable of up to 100 kHz switching frequency.
