A SINGLE PHASE TRANSFORMER LESS GRID INTEGRATED SOLAR PV SYSTEM WITH MPPT USING LUO CONVERTER

Viji R, Kirubhakaran T, Rajesh S

Abstract


The single phase transformer less grid with Luo converter is a type of a high-gain DC-DC converter that gives a positive output. Higher value of output voltage is obtained by using combination of   inductors and capacitors by using a single switch voltage gain is two times of that provided by a boost converter. The two stages re-lift configuration gives higher value of output from a low input voltage. In this paper, the re- lift configuration of Luo converter in continuous conduction mode with MPPT is presented and the relevant expressions are derived. This single switch converter in single phase transformer-less grid with maximum power point tracking from solar pv system is suggested. Simulation results are presented to support the theoretical analysis.
