MOSFET Heating Issue in Boost Converter with SG3525 and IRFB4110
I am working on a boost converter to step up DC voltage from 12v to 450v. My switching frequency is 45khz on each channel of the sg3525. I am using irf3205 as my switch. I observed that when i change the switches to another MOSFET like irfb4110 of higher rating the switch/MOSFET gets heated up even with no load at the output, has anyone faced similar issues before? my gate resistor is 10R and my gate to source resistor is 10k
