A high-efficiency CMOS voltage doubler

IEEE Journal of Solid-State Circuits, 1998
A charge pump cell is used to make a voltage doubler using improved serial switches. A complete power efficiency theory is presented which fits the measurements. The importance of capacitors is shown with plots of power efficiency versus load and stray capacitors.

Design of Maximum-Efficiency Integrated Voltage Doubler

2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007
In this paper, an algorithm and the analytical expressions to be used for the design of maximum-efficiency integrated charge pumps based on the voltage doubler architecture are presented. Starting from basic considerations on charge transfer, the proposed methodology allows adequate choice of the stage number and of the size of all charge pump elements,

A Low Ripple Current Mode Voltage Doubler

2015 IEEE 18th International Symposium on Design and Diagnostics of Electronic Circuits & Systems, 2015
Experimental results of a fully integrated low ripple charge pump voltage converter are presented. The pump is a current mode voltage doubler with a novel parasitic capacitance precharge mechanism for output voltage ripple reduction. A prototype of the pump was designed and fabricated in 130 nm CMOS process.

Yield optimization of a RSFQ voltage doubler

Journal of Low Temperature Physics, 1997
The centers-of-gravity optimization method has been applied to optimize a complex circuit consisting of a dc/SFQ-converter and RSFQ voltage doubler in order to obtain maximum parameter margins. As a result, the margins of all circuit parameters have been enlarged to at least ±35%. This improves the yield of the circuit fabrication process. On the other

Improved active‐diode circuit used in voltage doubler

International Journal of Circuit Theory and Applications, 2012
SUMMARYAn improved active‐diode circuit, which makes use of positive feedback to achieve fast on/off transition, is presented in this paper. The proposed active‐diode circuit can be embedded into a voltage doubler to replace the commonly used dead‐time circuit and to eliminate reverse current. In addition, the relationship between oscillation frequency,

A novel voltage doubler rectifier for high output voltage applications

The 2010 International Power Electronics Conference - ECCE ASIA -, 2010
By integrating a novel voltage doubler rectifier with a classical current-fed converter, a current-fed push-pull boost converter with voltage doubler (CFBCVD) is presented. In addition to having a non-pulsating input current, recovery of the secondary leakage energy, low output capacitor current ripple, much lower rectifier diode voltage stress, and ...

A zero voltage switching switched capacitor voltage doubler

2012 IEEE International Symposium on Industrial Electronics, 2012
Switched capacitor converter has advantages such as no magnetic components, compact size. With the target to reach high power, high switching frequency is preferred. In order to achieve high efficiency, soft switching becomes vital. This paper proposes a soft switched voltage doubler and its PWM scheme, with which, all switches in the converter turns ...

A power factor correction with voltage doubler rectifier

2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002
For small capacity rectifier circuits with a small capacity, such as those for consumer electronics and appliances, capacitor input type rectifier circuits are generally used. Consequently, various harmonics generated within the power system become a serious problem. Various studies of this effect have been presented previously so far. However, most of

Series resonant converter with output voltage doubler

TENCON 2010 - 2010 IEEE Region 10 Conference, 2010
This paper presents a parallel zero voltage switching (ZVS) dc-dc converter with series connected transformers. In order to increase output power, two transformers connected in series are used in the proposed converter. Two buck-type converters connected in parallel have the same switching devices.

Design of a CMOS cross-coupled voltage doubler

2016 IEEE ANDESCON, 2016
This paper describes a design procedure for a CMOS voltage doubler. Test-bench circuit are used to verify the performance of the design. Several equations that relate performance parameters with design variables are presented. This set of equations considers both transient and steady state behavior.
