These ripples are produced by the chopping effect of inverter switches, causing the DC-link current to fluctuate around the required average current, consequently requiring a large DC-link capacitor [11]. . In a single-phase photovoltaic power generation system, a 120 Hz ripple voltage occurs in the DC-link capacitor due to the use of a full-bridge inverter. Hysteresis relationship between the fuel cell voltage and current, and associated losses were analyzed in [8]. Moreover, authors in [9] reported a significant degradation of available. . This paper proposes an analytical formulation-based minimization of DC link current ripples for interleaved parallel inverter systems. Parallel inverter systems find applications in multiple fields. The interleaved superposition of the DC link currents in these systems can potentially be adjusted. . Again, a diagram shows the ripple measured as peak-to-peak, but the actual specification does not say peak-to-peak or RMS.
