Single-switch cell voltage equalizer using voltage multipliers for series-connected supercapacitors
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012A novel single-switch cell voltage equalizer using voltage multipliers for series-connected supercapacitors (SCs) is proposed. Since the proposed equalizer can operate with a single switch at a fixed duty cycle when operated in discontinuous conduction mode (DCM), the circuit complexity can be reduced significantly when compared with conventional ...

Reduced order model of the boost converter with voltage multiplier cell
XI Brazilian Power Electronics Conference, 2011The boost converter with voltage multiplier cell allows the extension of static gain by means of the switching capacitor technique, reducing the duty cycle needed to achieve the same voltage gain when compared to the conventional boost converter. However, the modeling of this converter is complex and requires the use of advanced techniques due to the ...

High voltage gain boost converter based on three-state switching cell and voltage multipliers
2008 34th Annual Conference of IEEE Industrial Electronics, 2008A new type of non-isolated step-up converter with high voltage gain is proposed on this work. It is suitable for applications with a high voltage gain between the input and the output stages. In this converter, the output to input voltage ratio, for a given duty cycle, can be raised by adding voltage multiplier stages of capacitors (mc).The theoretical

Modeling and Analysis of Modified Ultra-Lift Luo Converter Equipped with Voltage Multiplier Cell
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021The standard voltage boosting DC-DC converters may present a monotonically increasing or decreasing voltage gain. Nevertheless, to achieve significantly escalated voltage output, it is essential to employ voltage multiplier cells (VMC). Driven by this feature, a modified non-isolated ultra-lift luo converter (MULLC) based on VMC is adopted in this ...

A high step‐up isolated DC–DC converter based on voltage multiplier cell
International Journal of Circuit Theory and Applications, 2022AbstractGenerating sources of renewable systems, like photovoltaic module or fuel cell, have a low‐output voltage that has to be boosted for most of applications, such as grid‐tie inverters. To accomplish this, an isolated DC–DC high step‐up single‐ended primary‐inductor converter (SEPIC) with a Greinacher voltage doubler cell is presented.
