This paper presents a new inverter topology named after its operating principle based on a flying capacitor. The inverter uses neither a grid transformer (50/60 Hz) nor a high frequency transformer and therefore does not provide a strict galvanic isolation. However, its innovative circuit has been designed in order to allow grounding one pole of the photovoltaic (PV) generator which is not feasible...
This paper deals with the current trends in photovoltaics (PV) which are the use of new Silicon Carbide (SiC) transistors (sections II, III and IV) and the implementation of module integrated electronics (sections V and VI).
The total amount of photovoltaic (PV) energy production in the global energy mix has been increasing strongly all over the world in the last decade. This phenomenon has been mainly driven by the promotion of renewable energies, as well as by the well known feed-in tariffs. Although the major part of PV installations consists in roof mounted panels in private, collective or commercial buildings, the...
The new MOSFET-generation with SiC-materials seems well suited for power electronics converters up to 1200 V operating-voltage, and particularly for grid-feeding solar-inverters. Their high switching speed and low on-resistance RDS(on) allow the use of higher switching frequencies, which could mainly reduce the costs and weight of the converters. This paper shows a comparison between IGBT and SiC...
