Resumé

The impedance-based approach has been widely adopted to analyze converter-grid interactions. The dead-Time have a significant impact on the output impedance of the voltage source inverter (VSI), which will further affect the stability of the grid-connected VSI. The dead-Time can be elaborated as a nonlinear block, which highly depends on the output current. Moreover, the current ripple also has an impact on the dead-Time effect especially in light load condition, which is usually overlooked in previous work. This paper presents an accurate analytical model to characterize the dead-Time effect considering current ripple, which is established based on the double input describing function (DIDF). Both the simulation and experimental results confirm the accuracy of the proposed impedance model considering the dead-Time effects.
