For some reason when I use the ir2110 my circuit does nothing. Bootstrapping without it works perfectly. I’ve put the schematic I use in the down below (I got it from Tahmid’s blog). I’m using the irf3205 mosfet and the ir2110 mosfet driver. I’ve rebuilt it many times so I don’t think thats the problem. My only guess is that maybe the power supply for the bootstrapping ins’t a good one. I’ve using a 9V battery or 2 in parallel.
I’m using an arduino uno for the logic supply and the inputs. Any ideas as to why this is happening?
