The dynamic properties of a single‐phase transformer‐based inverter for ups systems

Abstract: SUMMARYThis paper presents two algorithms for the creation of an analytical model of a single-phase transformerbased inverter, using either the measurements of the control frequency-dependent characteristics of the inverter or the initial in-circuit frequency-dependent measurements of the transformer. The paper discusses how the parameters of the line transformer influence the dynamic properties of the inverter and, as a consequence, the design of the instantaneous control feedback loop. Line transformers, wid… Show more

“…However, none of these papers use the state space averaging method to create an equivalent model of the output impedance. The output impedances of the impedance networks implement 2 additional resonant frequencies to the control transient function that are very close to each other and to the fundamental frequency; thus, the damping resistances in the output impedance model determine the final change in the transient function …”
