Inductive components for solar power conversion in a harsh next decade environment

This paper presents a new 25 kVA PV inverter for a harsh next decade environment. To achieve the requirements new active and passive components are necessary. New Silicon Carbide (SiC) semiconductors together with a new cooling concept and an improved packaging shall lead in smaller passive components and thus to an increased power density of 1 kg/kW as wells as in a higher robustness against harsh environmental conditions. Additional calculated and measured efficiency results and an optimized passive components design are verified in a 25 kVA PV power converter demonstrator.
