Abstract:
The invention provides a solar photovoltaic three-phase micro-inverter, comprising DC terminals, connected with three DC photovoltaic assemblies for receiving DC; three single-phase inverter circuits, having DC input terminals connected with the DC photovoltaic assemblies via the terminals, for converting the DC to AC; AC terminals, connected with the AC output terminals of the inverter circuits and a three-phase AC power grid, for outputting the AC generated by the inverter circuits; wherein DC input terminals of each inverter circuit are connected in parallel with each other, and AC output terminals are connected with one phase of the three-phase AC power grid and a neutral wire via the AC terminals. The invention further provides a solar photovoltaic generation system. The invention connects DC sides of three single-phase inverter circuits in parallel, which can simply eliminate ripple power at DC side input terminals in a three-phase micro-inverter.
