A practical example of hard paralleling SiC MOSFET modules

Inhalt:
Is it possible to design a matched gate driver and power PCB to hard parallel four 6 mOmega 1200 V SiC MOSFET modules? This was the question that this paper sets out to answer. The practical results of this design project are described including: the gate driver schematics, PCB layout with the key tracking design issues, and waveforms of both static and dynamic current sharing performance. Finally, a Monte Carlo statistical analysis to demonstrate the effects on current sharing due to production spreads in device parameters such as on resistance.
