actually i am trying to build an invertor shown in the fig and i want to have power upto 100 watt so what do you suggest as for a heat sink
Quick calculation : 100Watt at 10V input voltage (neglecting efficiency of the system) = ~10Amps in the transistors.
The transistor you choose is not good. Maximum,specification only 6 amps. Hfe in the order of 30 for high currents, this means you should need 333mA base current at 10Amps, not good for the 555.
You need better transistors, probably darlingtons for this current level. And huge heat sink. For this power level, probably mosfets are better.
