is there anyway to increase an output voltage 100V DC to 110V DC using caps the source available is 110 V RMS?
With 110 V RMS sine, the peaks are 156 V.  Minus two diode drops, that should give you peaks of 154 V out of the full wave bridge.

With sufficient capacitance, you should definitely be able to get 100 V DC average out, assuming the rest of the system can handle whatever current your load takes at 100 V.
