Abstract

Generally, there is an input capacitor in front of PV(Photovoltaic) inverter in DG(Distributed Generation). This input capacitor mainly works in order to stabilize the PV output voltage. However, input capacitors, which are being used in domestic market are not well known about their appropriate value and also there is no information for selecting the suitable value of input capacitor. Therefore, the author suggests that the stand-alone PV inverter is considered to analyse appropriate value of input capacitor and then recommends the appropriate value of input capacitor through simulation.
