Abstract :
Using SiC MOSFET switches, this paper presents efficiency improvements in a dc-dc modular multilevel power electronic converter for wave energy extraction via electro active polymer. The total energy gain is estimated through a loss model for the SiC-MOSFET and compared with Si-IGBT based power electronic converter. Overall, in one energy cycle, up to 50% less energy loss was observed with the developed loss model. Finally, calculations performed using the developed loss model are verified in an experimental setup.
