Transformer-Less, Reduced Volume PV Inverter Topology
Inverters are devices typically used in solar power generation systems to convert electric current to a more useful type, but are prone to failure and are the main cause of malfunction in solar power systems. Using transformer-less (TL) inverters is a desirable alternative because of their higher efficiency, lower size, and lower cost. However, TL inverters...
