SINGLE-PHASE SINGLE-STAGE PV-GRID SYSTEM USING VSI BASED ON SIMPLE CONTROL CIRCUIT

摘要

Integrating electric energy generated by PV with utilities has been developed.\udSome of these using two-stage converters and the others using single stage\udconverters. For systems with two-stage converters, the first stage converter\udacts as a MPPT to maximize power generated by PV and the second stage is\udused as an interface to the utilities. In the single-stage system, an inverter is\udused for both function. In this paper, PV-Grid System using a single-stage\udVoltage Source Inverter is proposed. The simple control circuit to make PV\udgenerate maximum power and keeping power equilibrium between PV and\udinverter output power is used. To verify the analysis, simulations are done.
