Parallel Power Decoupling for Single - Phase Pv - Inverters – Making Film Capacitors Applicable

Abstract

Electrolytic capacitors are a bottleneck for inverter lifetime. Because of the large capacitances used in PV-inverters, a direct replacement by film-capacitors is not feasible for most topologies. This paper presents an active circuit which acts as an interface between the DC-link of a PV-inverter and an additional storage capacitor. By allowing a large… (More)
