Demystifying high-voltage power electronics for solar inverters
One of the key subsystems in PV generation is the inverter. Advancements in high-voltage power electronics are resulting in more intelligent, more lossless and smaller PV inverters.
Typical inverter efficiency curve as a function of DC input voltage. The rated input voltage will be a value around the middle of the allowed voltage range. Curves are also shown for higher and lower voltages, closer to the limits of the voltage range.
Reliability includes power module reliability, motor reliability, and isolation, and so forth. The architecture of a traction inverter varies with vehicle type. Plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) have a three-phase voltage source inverter topology, with power levels in the 100- to 500-kW range.
Inverters of low power can have efficiencies as low as 85–90%, whereas the best ones with higher power output and high input voltage can achieve 96%. 2015, Renewable and Sustainable Energy Reviews David Watts, ... Andrea Watson
The type 1 inverter presents a lower efficiency for small load (<30%), type 2 has the best efficiency whatever the percentage of load. Finally, the efficiency in type 3 decreases for high percentage of load in a more important way than for the two other types. 2017, The Performance of Photovoltaic (PV) System N.M. Pearsall
