Abstract :
Dc-dc converter control has major role in solar or photovoltaic (PV) systems with maximum power point tracking (MPPT). In this paper, analysis of multiphase boost converter for PV battery charging system is presented. Mathematical modeling of PV array and three phase boost converter is described and the simulation results are presented for 4.8kW PV array based battery charging system. Input voltage of the boost converter is controlled to regulate the maximum power point of the PV array. Input voltage control provides the advantage of easy functioning of MPPT algorithm. With the use of multiphase topology for the converter, the stress on power semiconductor switches reduces and additional benefit of reduced ripple current on PV array is obtained. Incremental conductance algorithm is chosen for the tracking of maximum power point (MPP).
