Assessment of Total Harmonics Effects on Grid-Connected Powered Inverter Using Sine-Referenced and Static-band Hysteresis of Current Controllers

Abstract

This article presents an assessment of total harmonics effects on grid-connected powered inverter using sine-referenced and static-band hysteresis of current controllers. To realize this art, current transducer, static-band and sine-referenced hysteresis current controllers, solar energy source, maximum power point tracker, grid supply and voltage source DC-AC converter are engaged. The system has these features are: (i) Light weight owing to none transformer-less system application (ii) Efficient in injection of power Under static-band hysteresis current controlled fed-back system, at upper and lower bands of 130Vand 50V, a total harmonic distortion, THD of 1.815% and output voltage, vo of 220Vrms (320V peak) were realized whereas in sine-referenced band hysteresis current controlled fed-back system at upper and lower bands of 430V and 340V, a THD of 1.019% and vo of 220Vrms are released. The computer simulations and spectral analyses of the system were presented
