| Descripción: | This work involves the design of an analog circuit operable as a gradient estimator for photovoltaic (PV) inverters. This is for a part of the process for the conversion of photovoltaic energy into electrical energy. The main objective of the estimator is to obtain two unknown parameters which depend on the temperature and the PV panel manufacturing intended to be used. This estimator design do not works for all PV generators, but for most of them, because the proposal covers the most common technologies currently used generators. The paper is basically divided in three parts.First, an explication of the theory and the proposal which is based on the design of this circuit is explained. Then, with block diagrams are illustrated the operation that should be in the different stages of the circuit, and finally the analog circuit configurations that are responsible for resolving each of the blocks that are explained. The final combination of these configurations accomplishes the goal of obtaining the two unknown parameters. |
