Hi.
I have built this SMPS that is designed by Yamaha with exact same components except for the IGBTs.
At first I have tried to use IFRP450 but after 5 seconds of operation IR2153 burnt out.
So I replaced them with IRF740 and this time my SMPS worked properly.
Since I had a pair of 2SK4106 I decided to give them a try but it resulted in another failure and IR2153 burnt out 5-7 seconds after power on!
My question is what could be possibly the problem? I am not an expert so I did not end up with a solution after studying the datasheets of these 3 components.
I appreciate any help from the professionals which can lead me to understand the physics behind this phenomena.
Thank you in advance.
