half bridge power supply schematic
I think in principle it will work. However, I found that IR2110 is a little too slow, so if you are running at high frequency, which I think you are, you may see problems with the delays introduced by the IR2110.
Another potential problem is the feedback for the main converter. I personally prefer the feedback from the output, but if the loads draw fairly constant currents, then this should work. I don't see anything fundamentally wrong with your schematic.
