I want to use the common heatsink for the Bridge rectifier,IGBT and Boost Diode.
I have calculated the Each of the Dissipation
P_DIS_Bridge=18w
P_Dis_igbt=24w
P_boost_diode=6w
RJC_BRIDGE=0.6DEGREE/W
RJA_BRIDGE=1.63 DEGREE/W
RJC_IGBT=0.58 DEGREE/W
RJA_IGBT=1.66 DEGREE/W
RJC_Diode=0.85 DEGREE/W
RJA_Diode=6.66 DEGREE/W
TJ=90 DEGREE
TA=50 DEGREE
How to calculate the common heatsink for all 3 power components...??
