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.

An improved voltage doubler in a standard CMOS technology

Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002
A charge pump cell is used to make a voltage doubler using improved serial switches. The PMOS transistor used for the serial switch is analyzed and a model ready for simulation is described. The importance of capacitors is shown with plots of efficiency versus load and stray capacitors.

A feasibility study on a voltage-doubler-type rectenna

2016 IEEE Wireless Power Transfer Conference (WPTC), 2016
We propose a voltage-doubler-type rectenna as a simple, compact and lightweight rectenna. As a feasibility study, we evaluate a 2.45 GHz voltage-doubler-type rectenna, in which Schottky diodes are mounted both in series and in shunt at the feed point of a half-wave dipole antenna, from measurements and circuit simulations. The measured rf-dc conversion

Voltage doubler application in isolated resonant converters

31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005
Two basic conditions of voltage-doubler adopted in isolated DC/DC converter are analyzed. According to the basic conditions, that voltage-doubler can be both adopted in LC series resonant converter and LLC multi-resonant converter. Operation characteristic of voltage-doubler adopted in isolated DC/DC converter is described in detail based on the ...

A Silicon-based Voltage Doubler: Preliminary Results

2006 3rd International Conference on Electrical and Electronics Engineering, 2006
This paper presents experimental results of a DC-DC converter based on the SC approach. In this design to power digital circuitry a 1.5 V voltage source has been used to emulate the energy to be supplied by a single battery. The voltage source is useful also to start the times2 operation.

Phase Doubler for high power voltage regulators

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
As the power consumption of microprocessors increases, a high phase count voltage regulator is required to meet the power hunger (>180A) and high efficiency requirements. In general, the higher the phase number count, the more PWM outputs and current sensing inputs are required for the PWM controller.

From a voltage divider to a voltage doubler for a large DC gain converter

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
A classical step-down switched-capacitor cell is transformed into a step-up cell. By inserting it in a boost converter, a single-switch, low voltage stress, non-pulsating input current, large dc gain hybrid converter is proposed. The theoretical, simulation and experimental results prove the merits of the simple new solution in comparison with the ...

A ZCS-PWM voltage-doubler rectifier with high power factor

2009 4th IEEE Conference on Industrial Electronics and Applications, 2008
This paper analyses and designs a zero-current-switching single-phase high power factor voltage-doubler rectifier. The proposed rectifier combines the conventional pulse-width- modulation technique, soft commutation technique and instantaneous average line current control to promote the circuit performance. Comparison with conventional boost rectifier,
