Using Calibration to Optimize Performance in Crucial Measurements
Cree Inc., a leader in silicon carbide (SiC) power devices, has introduced a fully-qualified commercial silicon carbide power MOSFET.
This establishes a new benchmark for energy efficient power switches and can enable design engineers to develop high voltage circuits with extremely fast switching speeds and ultralow switching losses.
The SiC MOSFET can be used for solar inverters, high-voltage power supplies and power conditioning in many industrial power applications. Over the next several years, SiC power switches and diodes could also expand into motor drive control, electric vehicles and wind energy applications. The market for power semiconductors in these applications is estimated at approximately $4 B today, reaching nearly $6 B by 2015.
The addition of the SiC power MOSFET to Cree's silicon carbide Schottky diode family enables power electronics design engineers to develop "all-SiC" implementations of critical high power switching circuits and systems with levels of energy efficiency, size and weight reduction that are not achievable with any commercially available silicon power devices of comparable ratings.
"This introduction of our SiC power MOSFET represents many years of materials research, process development and device design," said John Palmour, Cree Co-founder and Chief Technology Officer, Power and RF. "But the end result is that the industry's first 'ideal' high voltage switching device is no longer a future technology - it is commercially available and ready for design-in today. Together with our 600 , 650, 1200 and 1700 V SiC Schottky diodes, Cree Power has established a new class of SiC power components that are destined to lead the power semiconductor industry in the years to come, and eventually replace silicon devices in the majority of critical power electronics applications with breakdown voltage requirements of 1200 V or higher."
"Cree's release of the SiC MOSFET represents a major step forward in power technology and enables a new standard in performance and reliability to be reached," said Per Ranstad, Product Manager at Alstom Power - Thermal Services in Sweden. "At Alstom, we have been working with Cree to demonstrate the capabilities of this new device, in particular seeing its impact on energy efficiency in power systems, and we are definitely excited by the results we have achieved to date."
