Latest Patents

Abdolrahman Sajadi holds a patent titled "Switching transient based junction temperature estimation of SiC MOSFETs with aging compensation." This patent describes an apparatus and method for estimating junction temperature in a MOSFET by capturing switching transients in a source path. The measurement circuit detects voltage across a stray inductive element during the turn-on or turn-off phase and converts the transient into a pulse with a width proportional to the rise time or fall time. A processor determines the junction temperature based on the pulse width and stored correlations between transient durations and temperature. The system can be integrated into gate driver circuitry for real-time monitoring without substantial disruption to normal converter operation.
