Variable Speed Drives with SiC Technology

The S-PowerDrive is a state-of-the-art solution with extremely low harmonic distortion. This “clean,” high-power drive with very high efficiency is based on silicon carbide (SiC) technology, which has been extensively proven in the automotive and aerospace industries. It thus offers a compact design, low losses, and high power density for high-power process applications.

• Energy performance and overall efficiency

Energy optimization is a major challenge for industry. High-efficiency variable-speed solutions help reduce energy consumption, improve productivity, and lower the carbon footprint. When paired with the Dyneo+ motor, the S-PowerDrive forms a motor-drive package that maintains high efficiency across the entire operating range, including at reduced loads

• Ultra-compact design and reduced losses

The S-PowerDrive is an ultra-compact drive designed for environments where space is limited, without compromising on performance.

• 30% smaller footprint compared to IGBT technology
• 60% lower power losses compared to IGBT technology
• Easier integration thanks to a modular design

• “Clean” variable speed drive and harmonics control

Harmonics management is essential for maintaining the quality of the power grid and minimizing the strain on upstream equipment.
In the Active Front End (AFE) version, the S-PowerDrive:

• Limits total harmonic distortion to less than 5%
• Complies with the IEEE 519 standard
• Allows for smaller-sized transformers and upstream cables

• Power density and controlled thermal constraints

Thanks to SiC technology, the S-PowerDrive maximizes power density while ensuring reliability and performance, even at high switching frequencies

• Loss reduction
