For SiC MOSFETs, the real-time ${T_j}$ information is especially critical as limited field data are available regarding the reliability. In this article, utilizing the turn-on delay time as temperature sensitive electrical parameter, an online ${T_j}$ measurement is realized through an intelligent gate drive. Specifically, the turn-on delay time is translated into the pulsewidth of a digital signal through the conditioning/logic circuits. During ${T_j}$ measurements, the adjustable gate resistance circuit is activated to improve the measurement sensitivity beyond 600 ps/°C. Using the high-resolution capture module (300-ps resolution) in the system microcontroller, this pulsewidth is measured and then converted to junction temperature with a resolution of <0.5 °C.

The experimental results show that the response time of the protection circuit is within 110 ns. Without the proposed methods, the noise introduced by a low dv/dt of 2.5 V/ns will generate false-trigger protection actions. The improved protection circuit can survive under the dv/dt up to 84 V/ns, which verifies the validity of the proposed optimization methods.]]>362243224423983<![CDATA[Erratum to “Reconfigurable Hybrid Energy Storage System for an Electric Vehicle DC–AC Inverter”]]>36224432443509<![CDATA[Erratum to “Comparison of Wide-Band-Gap Technologies for Soft-Switching Losses at High Frequencies”]]>362244424451771<![CDATA[Erratum to “Hold-Up Time Compensation Circuit of Half-Bridge <italic>LLC</italic> Resonant Converter for High Light-Load Efficiency”]]>36224462446419<![CDATA[Erratum to “Modeling Avalanche Induced Degradation for 4H-SiC Power MOSFETs”]]>3622447244726<![CDATA[Erratum to “A Double-Modulation-Wave PWM for Dead-Time-Effect Elimination and Synchronous Rectification in SiC-Device-Based High-Switching-Frequency Converters”]]>3622448244824<![CDATA[IEEE Power Electronics Society]]>362C3C380<![CDATA[Administrative Committee]]>362C4C445
