Abstrac
The Photovoltaic energy shown an alternative
to meet the growing energy demand and reduce dependence on fossil fuels.
This paper makes an approach to the need to extract the maximum power
of photovoltaic panels via algorithms, such as the constant voltage. It
was also used a tracking algorithm based on temperature measurement, where
it returns the value of the reference voltage when a temperature change
occurs. To make the switching controller was used the one cycle control
- OCC by presenting a higher speed of convergence, disturbance rejection
of the source and no steady-state error. It was implemented in a DC-DC
Boost converter to extract the maximum power of the panel and was observed
that OCC is faster than PWM and the temperature algorithm was more efficient
than a pure constant voltage method.
