Discontinuous PWM for Online Condition Monitoring of SiC Power Modules [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 This paper presents the utilization of discontinuous PWM modulation for the condition monitoring of SiC power MOSFETs switching at high switching frequencies in a threephase inverter prototype. Due to the settling time imposed by the monitoring system, accurate measurements require low switching frequency and high modulation indexes when monitoring. To
