Abstract
Most of PV(Photovoltaic) inverters are utilizing voltage source type. Normally in this type, an input capacitor is connected at the input of a inverter to keep dc voltage constant. However, it does not seem to be well known how to determine the appropriate value of the capacitor. By developing non-linear transient analysis, the author suggest an approach to give a guideline. An Implicit trapezoidal formula was used to do this calculation.
