| Abstract: | A three-phase single-stage grid-connected photovoltaic inverter is introduced.The inverter starts up with voltage loop control and after start-up it changes to current loop control with MPPT starting to work.According to the characteristics of the MPPT methods,a method combining CVT,IncCond and fast-regulation is chosen with a good re-sult of MPPT.The inverter puts out active power to the electricity grid and it also can be conveniently controlled to put out certain reactive power for local loads as the rea... |
