Abstract :

In this paper the total work is done experimentally in which Solar PV DC Voltage has been converted into AC. In this Proposed work Microcontroller Plays a very vital role as 3 Phase Inverter needs to be given pulses and for this we have used a 725mA 1ϕ Transformer and the Transformer output which is AC is Converted in DC and this DC is given to the Series Voltage Regulator LM7805 and then the output of this Voltage Regulator is Fed to Microcontroller. Now, the Microcontroller Output is given to TLP250, which is an Octocoupler which drives the Gate Current of 3ϕ Inverter and Pulses is given to the 3 Phase Inverter. Now connect the Solar PV Module to Input of Inverter in which gets Output of 3 Phase Inverter in 120° mode & the Phase Voltage obtained is in the form of Quasi Square Wave.
