Closed Loop Sliding System with Grid Connectivity for PV Inverter using Controlled Quadratic Boost Converter

The present system is a Quadratic Boost Converter (Q B C) placed between a PV and a single phase inverter grid connected (SPI GC) system. This work suggests using a quadratic boost converter between the DC supply and inverter. The goal of suggested converter system is to control the load voltage of PV inverter system. This work examines the closed loop response of PV QBC SPI GC system using sliding mode controllers (SMC) and PI. Comparing dynamic response of closed loop SPI GC systems controlled by PI and SM allows for this. The Matlab results obtained show a developed dynamic performance with QBC SPI GC system under SM control. The results of PV QBC SPI GC system are compared to theoretical results.
