“…Since the analyzed Cuk converter had two inductors and two capacitors, two constraints were considered, one for each inductor current. A similar procedure applied to the single-ended primary-inductor converter (SEPIC) provided also third order small-signal transfer functions in [15]. More recently, some inconsistencies in the use of variables when using the state-space averaging method [12] have been revised in [8,16].…”

A previous article has presented the members of the asymmetrical interleaved dc/dc switching converters family as very appropriate candidates to interface between photovoltaic or fuel cell generators and their loads because of their reduced ripple and increased current processing capabilities. After a review of the main modeling methods suitable for high-order converters operating, as the asymmetrical interleaved converters (AIC) ones, in discontinuous current conduction mode a full-order averaged model has been adapted and improved to describe the dynamic behavior of AIC. The excellent agreement between the mathematical model predictions, the switched simulations and the experimental results has allowed for satisfactory design of a linear-quadratic regulator (LQR) in a fuel-cell application example, which demonstrates the usefulness of the improved control-oriented modeling approach when the switching converters operate in discontinuous conduction mode.

“…2. The converter fixes the output voltage if the input voltage is lower or higher than the reference voltage [4,5]. The SEPIC works cyclically by shifting energy between the inductors, the capacitors and the load.…”

This paper presents a method to maximize the power generated from a 3-turbine wind farm, and supply it to the grid with high power quality. Different control methods are applied to each subsystem; generation, aggregation, and finally grid connection. The control goal in the generation subsystem is to extract maximum wind power below rated wind speed, and to limit the power above rated wind speed. The aggregation subsystem employs three fuzzy logic-controlled bi-directional DC/DC single ended primary inductance converters (SEPIC) for DC power collection with fixed voltage. The subsystem connecting the wind farm to the grid is controlled to improve the power quality of the system. Power quality improvement is done via a vector-controlled currentregulated PWM inverter for synchronization to grid with unity power factor while minimizing current harmonics. The proposed system is modeled and simulation results presented proving the power quality improvement.
