Abstract
<p>This paper presents a semi-open-loop control for a single-phase grid-tied inverter with voltage control. To improve the output current distortion, a disturbance observer, including an inductance value greater than the grid-tied inductance, is applied to semi-open-loop control. Using the proposed method, the inverter output current total harmonic distortion (THD) is reduced by 76% with the grid-connected operation compared to the open-loop control. Moreover, the THD of the inverter output voltage is reduced by up to 57% with the stand-alone operation for a diode rectifier load.</p>
