Thermal Simulation and Measurement for EV charger Full SiC Power Module

Recently, electrical vehicle (EV) charger demand has been grown rapidly due to electrical vehicle development, so we designed a full SiC power module for EV charger system. The power consumption and thermal performance of EV charger module were evaluated by simulation software. Besides, we did the thermal resistance measurement of full SiC module and calibrated the Rjc (junction-case) .The simulation results show that we can reduce the size of heatsink because of higher system efficiency caused by full SiC power module. The advantage of using SiC chip in EV charger power module lose less power than silicon power module because of SiC chip's electrical characteristic.
