A power converter that can withstand 200 °C

Researchers at Leti have tested in real-world conditions a power converter capable of operating at an ambient temperature of 200 °C (and up to around 250 °C). High temperatures like these are common in automotive, aeronautics, and oil and gas drilling applications. Leti’s technology could also reduce—or eliminate entirely—the need for cooling systems in less-demanding everyday applications like elevator motors, HVAC systems, and residential pumping equipment.

The converter leverages a novel technology: a line driver with adaptive output impedance that adjusts switching speeds from 20 nanoseconds to 200 nanoseconds depending on the use environment and risk of electromagnetic disturbances. Several patents have been filed to protect the innovation.
