Multi-proposal utilization of One-Cycle Controller in photovoltaic systems for DC applications

This paper proposes the utilization of One-Cycle Controller (OCC) for multi proposal tasks in photovoltaic (PV) systems that supply power to DC applications. The photovoltaic system proposed in this paper is composed of one PV panel and two DC-DC converters connected in series: one for track the maximum power point and the other to regulate the bus voltage for DC applications. Both of the converters are switched by controllers that utilize OCC modulation instead of the classical Pulse Width Modulation (PWM). The results in this paper show that OCC is a multi-objective modulation technique that provides faster transient response than PWM technique, good reference tracking and robustness to the system preventing the loads reduce their useful life or be damaged permanently.
