The present paper relates to “Power Conditioning Unit”. The system uses Z-source type inverter as a power conditioning device. The energy demand is increasing day by day, after various analysis by different researchers it is observed that solar systems are superior options due to its fresh, non-polluting, and never ending nature. There is an intermediate stage when power processes from source to the load and this stage comprises of “Power Conditioning unit”. This unit converts sun radiations into electrical form of energy. Generally this unit consists of inverters. In this work, a different method is used by joining ZSI into PCU which offers a single stage power transformation. In the projected scheme ZSI is also integrated with MPPT. Normal boost control scheme is used for providing gating control signals which makes the system more efficient and decreases THD.
