Abstract: Parallel connection of inverters is one useful method for solving the high power requirements. It reduces the current stress on inverter switches and makes the way for continuous supply to the load.Though any one of the inverter supplying the load gets faulted, the other inverter connected would supply the load. But the problem in this kind of set up is that it needs synchronization techniques for parallel operation or else the inverters will operate in unsynchronized manner and the supply would be in distorted form for the motor load leading to overheating of the load. This paper proposes two software drive control techniques for the parallel operation of inverters in synchronized condition. These software techniques are implemented and results are analysed in the MATLAB environment.
