This article presents the design, implementation, and analysis of the results of a constant duty cycle solar charge regulator to be used in autonomous photovoltaic systems based on lithium-ion batteries. The regulator works with a constant duty cycle, dispensing with feedback from the battery state of charge, reducing complexity and cost. A simulation of autonomous photovoltaic systems is performed to help to explain how the regulator works. In addition, the main design aspects are presented to be compared experimentally with commercial regulators under identical test conditions. In conclusion, the constant duty cycle solar charge regulator suitably achieves the lithium-ion battery full charge and also, it presents an intermediate efficiency with the regulators more complex with a feedback loop. Like, are the maximum power point tracker regulator and the pulse width modulator regulator. In conclusion, the constant duty cycle solar charge regulator is a cost-effective solution, and it is appropriate to be used in autonomous photovoltaic systems.
