A Performance study for two current sensor free single-cell maximum power point tracking methods for high performance vehicle solar arrays

Two Maximum Power Point Tracking (MPPT) control algorithms have been previously developed for the single high performance dual junction or triple junction solar cells for hybrid and electric vehicle applications. These algorithms are respectively based on the Perturb and Observe (P&O) and the Incremental Conductance (IncCond) methods but remove the need for current sensing devices. This paper provides a comparison of the two MPPT control algorithms and a detailed performance evaluation of the two algorithms under both static and dynamic tests. The Incremental Conduction algorithm achieved slightly better results and static tracking accuracy of 99% .
