摘要：There are so many topologies of DC-DC converters are used in Grid connected PV system among all those topologies the PI controlled dc-dc Zeta converter with soft switching provides the best result among all and which is more suitable for both IC and P & O algorithm. This topology is also suitable for switching between two different MPPT algorithms. In this paper the MATLAB simulation performance analysis of combination of PI control and soft switching techniques. This performance analysis of this combination of techniques of a grid connected PV system finds the better suitable converter which can give the output with maximum power from the PV module and can have reliability to connect it to the GRID. .
