Digital controllers design analysis for DC/DC converters in PV applications

The development on photovoltaic (PV) applications along with recent breakthroughs in power electronics and processors technologies, has became in a strong research area especially in modeling and control techniques, for which digital controllers offer some advantages over analog controllers; however their design does not always lead to accurate performances. This paper proposes to adopt an analog design of digital parameters, which provides the digital controller parameters to ensure a correct operation of the maximum power point tracking (MPPT) algoritmth, fulfilling analog design ensuring system stability, low cost and implementation complexity.
