Abstract

In this paper a new high gain converter operating under Particle Swarm Optimisation based MPPT technique is discussed. This converter is double switch double inductor single capacitor-based converter and produces a gain of (1+D)/(1-D). The circuit consists of 2 switches, which are triggered together, thereby aiding the process of feeding MPPT to it with ease. MPPT technique which is prominently used is of conventional type, like PO, InCond, etc. These types of techniques fail with partial shading problems and takes time in tracking back, so optimisation technique stands overpoared among conventional methods. Henceforth, in this paper PSO optimisation technique is utilised. The results of the simulation have been presented along with the comparison between InCond and PSO method. The whole system discussed here stands out to be the initial stage of PV grid system. It finds application in rooftop planted solar grid system and helps the user (household) to earn more by supplying most available power to grid supply.
