This paper focuses on simple technique from conventional techniques for the rapid maximum power point (MPP) pursuit with a less oscillations under sudden changes. In investigations, the controllability of the conventional boost converter model shows that the converter can be controlled from the current of its inductance (inductor). To get reference current, a conventional technique known as method of short-circuit current has been transformed to clearly establish with supporting evidence an estimated photocurrent. Different test was done on MATLAB/Simulink under irradiance, temperature and load changes. Facing the P&O and short-circuit method, the proposed method presents a response time of 11.08 ms and power variations at MPP around 0.1 Watts. A test made on another converter shows that this method can be applied on DC-DC converters where the inductor current need to be controlled for proper operation.
