At this moment, the major
obstacle of wide PV system commercialization is the
high initial investment cost that stems from the strict
grid connection standards and high expectations from
the PV system [2], [3]. The grid-connected PV system

To keep overall output power per
unit cost low, the grid-connected converters should be
able to extract the maximum available power from the
PV arrays. Since the PV array characteristic is highly
nonlinear, maximum power point tracking (MPPT)
