The photovoltaic maximum power point tracking (MPPT) algorithm based on incremental conductance is found to have an error mode which prevents its normal operation under conditions of rapidly changing/oscillating solar input (insolation). An enhancement to the algorithm is investigated and experimentally evaluated. It can be readily added around an existing MPPT algorithm to enable it to be used more reliably in mobile applications.
