Someone will probably mention it, so it might as well be me. Are you aware that you can kill yourself (or others) easily with 110VDC? What is the source of that voltage? Is it mains isolated?
I may be wrong, but it sounds like you may be an electronics novice so my advice is no, you cannot!
Both 110VDC and AC are very dangerous so if you need an inverter I suggest you buy a commercial one.
