Design and implementation of closed loop controlled boost converter for solar power installation system using fuzzy logic controller

Green energy resources are an interesting, readable solution to achieve global sustainability. This paper proposes a controlled approach to achieving a constant voltage despite of change in load and supply voltage for a solar photovoltaic system based application. Modeling of the system is very essential before installation of the system, which produces an enhanced robust planning for the required load. It also helps to achieve the system reliability and robustness at the load center. For the control of nonlinearity present in the designed system, fuzzy logic technique plays a key role to achieve a desired behavior of controlled output voltage. Hence, the fuzzy logic control scheme has been implemented in the system with power electronics interfacing units to stabilize the output voltage at load side. For its effectiveness, result is examined and compared from open loop system.
