| Abstract |
This paper proposes an advanced Incremental
Conductance MPPT algorithm with a variable step size for
a solar array regulator (SAR) system. This approach adjusts
automatically a step size to the solar array operating point,
thus improving the MPPT (Maximum Peak Power
Tracking) speed and accuracy compared with the
conventional method with a fixed step size. For the analysis
of stability of the proposed algorithm near the maximum
power point, the small signal modeling is carried out. Also,
it is verified by experiment using a 180W parallel connected
prototype hardware. |
