Comments on "Unified Analysis of Switched-Capacitor Resonant Converters"
The realization of line and load regulation in switchedcapacitor (SC)-based converters is discussed. A duty-cycle control is based on partial charging of the capacitors in the circuit. The influence on the efficiency is pointed out. The use of inductors in SC-based converters is discussed.
متن کاملSteady-State Characteristics of Resonant Switched Capacitor Converters
Conventional switched capacitor converters have an inherent drawback that their efficiency decreases as the output current increases. This inherent drawback is due to a periodical forced charging and discharging operation in the internal switched capacitors accompanied by a large capacitor current. Their efficiency can not be increased by decreasing its internal resistance. As a result, convent...
متن کاملResonant Switched Capacitor DC-DC Converter with Stackable Conversion Ratios
As the demand for fully integrated power management system has increased in recent years, the switched-capacitor (SC) converter has shown exceptional promise due to the favorable energy density of capacitors, but its limited output range and its intrinsic charge-sharing loss have limited its range of applications. In this paper, a resonant switched-capacitor (ResSC) topology is presented as a w...
متن کاملSwitched Capacitor Filter
A Switched Capacitor circuit is an electronic circuit element used for discrete time signal processing. It works by moving charges into and out of capacitors when switches are opened and closed. Usually, nonoverlapping signals are used to control the switches, so that not all switches are closed simultaneously. Filters implemented with these elements are termed switched capacitor filters. Unlik...
متن کاملComments 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...
