This paper investigates nonlinear control methods for single-ended primary-inductor converters (SEPIC). The fast-switching and average models show the converter nonlinearity in terms of inductor currents, capacitor voltages, and the switching duty cycle. The control law intuitively should be nonlinear to drive and guarantee the system stability. Two different control laws based on the passivity and...
DC-DC converters face an exponential growth in the context of the ever-increasing use of DC grids, namely at the home and business levels. In this domain, efficiency and reliability are of major concern. Solutions already available in the literature concerning fault-tolerant DC-DC converters do not consider the application of such converters in household environments and their constraints. To solve...
This paper proposes an energy storage unit integrated dual input PV system with distributed maximum power point tracking (MPPT). Through applying a symmetrical configuration, the proposed PV system has a single stage structure to implement voltage boosting and inversion, which contributes to the advantages such as compact size and high power conversion efficiency. The design of the control strategy...
