Abstract

In this paper, the stability of solid state transformer (SST)-paralleled inverters system is investigated by using the unified impedance-based stability criterion (UIBSC). Theoretical analysis reveals that the output impedance characteristics of SST are frequency-dependent and multiple resonances can happen in the SST-paralleled inverters system. A lead-lag… (More)
