“…The power switch is derived under 50% of the duty cycle D = 0.5. Based on Equation (19), for the input voltage equal to 24 V DC, a voltage with around 240 V DC amplitude at the output of the converter is expected. Figure 8A presents the input and output voltages and shows that the desired voltage has been obtained.…”

“…Generally, power converters are time-varying nonlinear systems, and due to the uncertainty of the converter parameters, their ability to be accurately modeled in all operating conditions is extremely difficult, so the control process for the power converters is always a major challenge for designers. [17][18][19][20] Therefore, normally the single-switched converters based on need only one control block is selected by engineers. The efficiency of the converter is limited by the active power switches, diodes, capacitors, and inductors serial resistances and therefore the cascaded boost converters due to their more components numbers are not recommended.…”

Many of the photovoltaic (PV) panels generate the low amounts of the voltages under the limited values of the powers. In order to increase these voltages to be applicable for grid utilization, DC-DC boost converters are used. A novel nonisolated transformer-less switched-capacitor-based DC-DC power boost structure is combined with the quadratic converter in this study. The proposed converter has many advantages such the low-voltage stresses on the power components, higher voltage-gain, and ability to supplying the load under the low amounts of the switching time intervals. These features lead to fewer amounts of the currents for the power components in the topology for the continuous conduction mode which means less dynamic losses and higher efficiency. Another advantage of the proposed converter is including only one power switch that simplifies the controller design for implementation purposes. A comprehensive mathematical analysis is presented and simulation with MATLAB/SIMULINK and implemented hardware test results confirm the theoretical investigations.

“…One of the mandatory requirements of the modern dc power supplies is to maintain the output load voltage at desired set point by automatically adjusting the duty cycle against any drift in supply voltage, load current or any external disturbance. Classical state space averaging techniques can be useful in developing the small signal model of the hardswitched power converter [15][16][17], operation of which in continuous conduction mode (CCM) is completed within two modes (active mode and passive mode) in a switching cycle. Conventional closed-loop controllers are designed based on the system transfer functions, obtained from the small-signal model of the converters.…”

“…Conventional closed-loop controllers are designed based on the system transfer functions, obtained from the small-signal model of the converters. In [15] a contoured robust controller bode plot has been used to design the voltage-mode controller for a fifth order boost converter. This controller enjoys the advantages of more freedom in placing the poles and zeros and achieve better stability margin compared to conventional PI controller.…”

This paper presents a novel zero-voltage zero-current transition DC/DC buck converter, which uses an active auxiliary resonant network to achieve soft switching operation of semiconductor switches and soft-recovery of power diodes over wide output power range and offers high efficiency. The auxiliary cell in the proposed converter does not cause any additional current stress on the semiconductor switches and has minimal impact on overall dynamics of the converter. Steady-state performance of the converter has been presented with detailed theoretical analysis of all operating modes. The design of auxiliary cell components and development of small signal model of the converter have been carried out from the mathematical equations depicting its dynamic behaviour. A closed loop voltage mode controller with a type III compensator has been developed for the converter to achieve the desired transient response under the influence of external disturbances. Power loss analysis and superiority of the proposed converter over other conventional configurations are also presented here. Finally, soft-switching behaviour and step-input transient response of the converter are verified by hardware experimentation on a150W, 100 kHz prototype model. The experimental measurements have successfully validated the theoretically predicted behaviour of the converter.INDEX TERMS Buck converter, Soft-switching, Zero current switching (ZCS), Zero voltage switching (ZVS)

“…Having identical voltage gain as SL-based boost converter and the topology reported in previous works, 7,8 various step-up boost dc-dc converters are also reported in recent literature. [9][10][11]21,22 However, in these topologies, higher numbers of passive elements are utilized to achieve a lower boost factor. A KY boost converter is suggested in Hwu and Yau 12 to achieve high voltage gain at a lower and moderate duty ratio by utilizing two switches, two inductors, and three capacitors.…”

In this paper, a new family of non-isolated boost dc-dc converters with high voltage gains is proposed. The proposed boost topologies exhibit very high voltage gains at moderate duty cycles and lower switch voltage/current stresses with reduced component counts. Here, a total of four new non-isolated boost topologies are proposed using four-terminal PWM high-gain switch cells with an inductor-switch network. Among these four topologies, two converters have identical voltage gain with opposite load voltage polarities and likewise other two exhibit similar nature (i.e., equal but opposite load voltage) but have higher gain than the former topologies. The detailed operating principle, steady-state analysis, and design methodology are presented for the proposed positive output very high-gain converter, which can be easily extended to the rest of the topologies. An exhaustive comparison study has been presented for the proposed topologies with the existing step-up converters to highlight their advantages. Finally, the mathematical analysis, analytical studies, and high boosting feature of the proposed positive output high-gain boost converter are verified using a 250 W, 50 kHz prototype. The experimental results are presented for different duty cycles with fixed input voltage to verify the efficacy of the proposed structures in terms of higher boosting capability.
