Technical Article: SiC MOSFETs Enable High Frequency in High Power
Conversion Systems

High power converter designers have always had to strike a balance between performance, size, cost, and operating switching frequency (Fsw). Higher Fsw results in smaller and lighter converters, but they pay a penalty in efficiency. Typically, for high power systems (>500kW), the balancing act results in an optimal Fsw of about 3 kHz. All-SiC power modules now allow design engineers to design to higher Fsw without a significant penalty on performance, tipping the scale in favor of higher frequency power conversion systems, which can result in smaller size and weight, faster response times, simplified, and more reliable power conversion systems.

White Paper: Measuring SiC Schottky Diode Ruggedness with A High Voltage Pulse Generator
When the first generation of silicon carbide Schottky diodes was introduced more than 10 years ago, their widespread adoption was somewhat challenged by unforeseen dV/dt limitations within certain manufacturers’ devices. In particular, devices with lower dV/dt capability were susceptible to failure from large in-rush currents. An initial reliability study of some of these early 600V SiC Schottky diodes reported an upper dV/dt limit of 55–60V/ns (volts per nanosecond), which unfairly tarnished the reputation of SiC diodes in general. Observing that their SiC Schottky diodes were not included in the initial study, researchers at Cree (now Wolfspeed, A Cree Company) performed a subsequent reliability study on their first-generation 600V SiC Schottky diode, and demonstrated that their SiC diodes could withstand a turn-on rate of 75V/ns and a turn-off rate of 100V/ns for more than 100,000 cycles without failure.
