I ordered a couple of IR2153D chips and a few high voltage Mosfets today to begin experimenting with a half bridge ~200-250W power supply. I have ETD39 cores and bobbins on hand so I will use them for the transformer. What is the best 2153 design on the diysmps site to use as a basis for design? Or is there a design somewhere in Google world that could be used as a starting point? I will be running the supply from 120 V line supply so I will use a voltage doubler to get the ~330V bulk supply.
In the initial design I am going to power the IR2153 with an external 15V power supply so I won't have to deal with start up issues and possibly blowing the 2153 and/or Mosfets. After I have the supply running I'll work out something to have it start from the bulk supply and delay turning the Mosfets on after a slight delay.
Any pointers or suggestions are appreciated.
