Functionalities will be added for online monitoring of the Power devices including:
• Online monitoring of VDS for device health assessment. This will be done by modifying the existing gate driver circuitry.
• Online estimation of the device junction temperature by measuring the base plate temperatures and feeding the data to a detailed thermal model of the designed converter.
• Active modulation of the gate resistance during the switching transients to control the voltage and current overshoots of the power devices. The static characterization of the XHV-6 modules will be done to figure out the variability among the different modules. Furthermore, several protection features will be added including AC and DC short circuit protection, AC and DC over voltage and over current protection. We will attempt to create a user interface to be implemented for the end users which will show real time date of the MUSE SST system.
