Cover Story
Robust Construction of Optoisolator

The concept of functional safety revolves around the assurance that a system will behave in a predictable and safe manner, even when faced with internal faults or external disturbances. In the context of motor drives, this entails implementing measures to mitigate risks associated with electrical, mechanical, and software failures, ensuring that the system operates reliably under all foreseeable circumstances and prevent injury, damage, or even loss of life.

Packaging
An Advanced Isolated Discrete Package to Keep SiC MOSFET Chip up to 60°C Cooler

Isolation of conventional discrete SiC MOSFETs from heatsinks relies on an external, thermally conductive, electrically isolating material. This not only increases thermal resistance junction-to-heatsink, but also complicates thermal management and creates obstacles in both automated and manual assembly processes. Furthermore, poor thermal conductivity reduces power and current handling capabilities, significantly limiting optimal SiC chip utilization. The ISO247 package from Littelfuse, featuring high performance silicon nitride (Si₃N₄) ceramic, addresses these challenges, improving SiC chip utilization and enhancing SiC MOSFET based applications.

Power Supply
Addressing Next-Generation System Power Demands

Global electricity consumption will grow by 3.5% over the next few years1 driven by increased demand across all sectors, not least energy-intensive industrial applications and data centers addressing demand requiring processing capacity for artificial intelligence (AI) and machine learning (ML). At the same time, legislative, environmental and operational cost challenges put pressure on designers and system architects to deliver optimized power supply and conversion technologies that support ultra-efficient and scalable power delivery in the smallest possible form factors. Here, Advanced Energy looks at how highly efficient and configurable power supplies can address this need with sustainable, high-density power architectures for the future.
