“…Moreover, in Morales-Saldaña et al (2014), the authors provide a QBC based on the reduced redundant power processing (R 2 P 2 ) principle, as well as, on a controller design methodology using current-programmed control satisfying the specifications about output voltage regulation. Chen et al (2016) shows a QBC with a higher Power Factor Correction (PFC), obtained from a variable duty-cycle control. Alonge et al (2017) proposes a transformer-less single switch topology of QBC.…”

This paper deals with a control strategy for a DC-DC quadratic boost converter. In particular, a hybrid control scheme is proposed to encompass a control law and an observer for the estimation of the system states, based only on the measurements of the input and output voltages. Differently from classical control methods, where the controller is designed from a small-signal model, here the real model of the system is examined without considering the average values of the discrete variables. Using hybrid dynamical system theory, asymptotic stability of a neighborhood of the equilibrium point is established, ensuring practical stability of the origin, which contains estimation and tracking errors. Experimental results show the effectiveness of the proposed approach.

“…All these mentioned works, except few cases (Chen et al, 2016;Lopez-Santos et al, 2015), are based on a constant switching frequency, changing the duty cycle for tracking the voltage reference. Moreover, the design of the controller is based on a small-signal model obtained from the averaged statespace system.…”

This paper presents and analyzes an AC-DC power converter structure, which is comprised of a Power Factor Correction (PFC) module and a LLC resonant DC-DC converter module. This converter only uses two switches, and requires three less diodes and one less switch compared to popular LLC resonant converter solutions. Compared to its conventional counterpart, the rectifier of interest has high energy efficiency while a smaller size, owing to the soft-switching in the LLC resonant converter. Detailed theoretical analyses are conducted in this study, followed by software simulation and hardware experimentation, which demonstrate that the single stage double-switched (DS)-LLC rectifier is able to realize unity power factor and a wide output range, indicating its effectiveness and applicability.

“…Therefore, it could be a low cost and efficient solution capable of achieving a high-voltage-gain with a relatively low control complexity [8]. Recently, this topology has attracted the interest of many researchers in different power electronics applications such as in power factor correction [9], in fuel cell energy processing [10], in PV systems [11], [12] and in DC microgrids [13].…”

In this paper, the nonlinear dynamics of a PV-fed high-voltage-gain single-switch quadratic boost converter loaded by a grid-interlinked DC-AC inverter is explored in its parameter space. The control of the input port of the converter is designed using a resistive control approach ensuring stability at the slow time-scale. However, time-domain simulations, performed on a full-order circuit-level switched model implemented in PSIM© software, show that at relatively high irradiance levels, the system may exhibit undesired subharmonic instabilities at the fast time-scale. A model of the system is derived, and a closed-form expression is used for locating the subharmonic instability boundary in terms of parameters of different nature. The theoretical results are in remarkable agreement with the numerical simulations and experimental measurements using a laboratory prototype. The modeling method proposed and the results obtained can help in guiding the design of power conditioning converters for solar PV systems, as well as other similar structures for energy conversion systems.
