چکیده
The increasing interest in renewable energy sources has brought attention to large voltage-gain dc–dc converters; among the different available solutions perform a conversion, this article presents an overview of non-isolated converter topologies that utilize switched-capacitor circuits, i.e., diode-capacitors voltage multipliers. review includes combinations traditional power stage with diode-capacitor-based multiplier, such as multilevel boost converter. This starts by reviewing (SC) topologies, and types charge exchange; it provides straightforward analysis understand discharging losses. It then covers other recently introduced state-of-the-art. Special is put on SC circuits resonant interchange have been probed achieve very good efficiency. An additional contribution new proof losses focused initial final stored capacitors, explains relatively efficiency obtained converters.

Comments and Corrections Comments on “Design and Analysis of Switched-Capacitor- Based Step-Up Resonant Converters”
With reference to a recently published paper, the realization of line and load regulation in switched-capacitor-based converters is discussed. We point out that achieving zero-current switching at the expense of losing line and load regulation is not practically feasible. In [1], a way of realizing zero-current-switching (ZCS) in step-up switched-capacitor (SC) converters has been presented. Th...

The mass usage of traditional fossil energy has adversely affected the environment on a global scale, such as environmental pollution and greenhouse effect. Meanwhile, there has been a growing demand for energy with the development of society. Since traditional fossil energy is not renewable, it is faced with the problem of energy shortage. Solar energy and hydrogen energy are promising, and ph...
متن کاملStep-Up Switched-Capacitor (SC) AC-DC Converters for RFID Tags
In signal processing circuits of a RDIF tag, the relaxation of restriction concerning operating voltage range enables us to develop various applications. In order to provide higher voltage to the signal processing circuit, two types of step-up AC-DC converters for RFID tags are proposed in this paper: the step-up converter and the step-up converter. To reduce ripple noise of output voltage, the...
