Abstract
The Power Converter with MPPT controller is a heart of any solar PV system. The basic MPPT controller is capable to learn non-linear I-V characteristic of PV system and search an optimal point where power output is maximum, known as Maximum Power Point. In case of Partial shading, I-V curve is highly non-linear with multiple power points and simple MPPT is not capable to trace out MPP point. The various improved MPPT methods are developed for tracking MPP under partial shading condition. In this paper, improved MPPT method is discussed and implemented. The simulation based analysis is carried out for performance analysis.
