Conversion efficiencies of six grid-tied inverters at the Tucson electric power solar test yard

This paper analyses the impact of operating modes 1 and nonideal power supply conditions on the efficiency of modern 2 low-voltage power electronic devices. The sophisticated circuits 3 and controls implemented in such devices are expected to result 4 in increased efficiencies, higher operating power factors, and 5 reduced harmonic emissions. However, the interactions of individ-6 ual PE devices with the supplying network will impact exchanges 7 of powers at fundamental system frequency and nonfundamental 8 (i.e., harmonic) frequencies. This paper correlates the obtained 9 results for harmonic performance and efficiencies over the entire 10 range of operating powers of the considered PE devices using 11 both standard definitions and some alternative interpretations.
