Parallel diode to SiC-MOS: to Be or not to Be? Intrinsic Body diode Additional Fast Series & Parallel diode Additional Parallel diode Si-MOSFET SiC-MOSFET SiC ADVANTAGE Poor Reverse Recovery Characteristics Low Vf Blocking series diode mandatory to avoid slow body diode to conduct No advantage: Current flow would go to body diode only Good Reverse Recovery Characterisitcs. Higher Vf No Need for blocking diode Mandatory to reduce high conduction losses of body diode Low SiC diode switching losses Less components count and less conduction losses Allow full SiC-MOS performance without limitation of body diode losses SiC-MOS Body diode is enough when operated at low duty cycle SiC-MOS parallel diode required if operated at high duty cycle Parallel diode can be avoided if SiC -MOSFET is turned ON (Synchronous Rectification) 2014 Microsemi Corporation 7
SiC-MOS VSD performance vs VGS APTMC120AM20CT1AG VSD curves vs ISD at given VGS values The lower the negative gate voltage the higher the Vsd The higher the positive gate voltage the lower the Vsd To minimize the diode conduction losses the SiC-MOSFET should be turned ON with VGS = 20V 2014 Microsemi Corporation 8
SiC-MOSFET gate drive Example of Opto-driver gate driver that can be used to drive SiC Mosfet Increasing Gate voltage to 20V reduces total losses by 30% Negative gate bias further reduces losses, but the impact is smaller than for IGBTs Vgs voltage range should be within -5V to +20V to optimize total losses 2014 Microsemi Corporation 9
