Abstract:
The utilization of solar energy has grown in the last decades, and due to the scarcity of fossil fuels and the awareness of the increasing greenhouse gases in the atmosphere, this energy tends to become predominant. For generating photovoltaic energy, photovoltaic modules are connected to converters to define the amount of energy provided to a load. A maximum power point tracking method is used to maximize the photovoltaic module output power considering the solar radiation and panel temperature. This work proposes the implementation of one-cycle control (OCC) to track the maximum power point of a photovoltaic module in direct current converters. This paper contains an analysis of response speed, reference tracking and transient, showing the applicability of the OCC technique
