Performance Limits of Switched-capacitor Dc-dc Converters
Theoretical performance limits of twophase switched-capacitor (SC) dc-dc converters are discussed in this paper. For a given number of capacitors k, the complete set of attainable dc conversion ratios is found. The maximum step-up or stepdown ratio is given by the k t h Fibonacci number, while the bound on the number of switches required in any SC circuit is 3k 2. Practical implications, illust...
متن کاملComments 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 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...
متن کاملSoft Switched Resonant Converters with Unsymmetrical Control
Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated l...
