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...
This paper investigates the operation principle, modeling, and control of a hexagonal converter for grid connected photovoltaic (PV) systems. The hexagonal converter is composed of six conventional two-level voltage source converters (VSCs) in which each VSC module are connected to a string of PV modules. The equivalent circuit model of the proposed topology is first detailed in the abc reference...
At present, the field of power factor corrected (PFC) rectifiers are very much matured. Typically a single phase PFC converter requires measurements from three independent sensors i.e. input voltage, input current and output voltage. By considering a need of farther compact and more flexible in terms of input to output voltage gain, a new UPF rectifier with two buck-boost converter operating in interleaved...
