Work in Progress: Output Impedance Specification of A Three-Phase Current-Source Inverter for Modular Photovoltaic Applications

Impedance-based stability assessment has been an important part of renewable integration. Modeling and measurement of impedance under Synchronized Reference Frame (SRF) is a common way for a portrait of the frequency-dependent impedance. In this paper, a modified current-source inverter (CSI) called...
