A Step-Up DC–DC Converter With a Resonant Voltage Doubler [PDF]
IEEE Transactions on Industrial Electronics, 2007 A step-up dc-dc converter with a resonant voltage doubler is proposed. The proposed converter is composed of an active-clamp circuit and a resonant voltage doubler. The active-clamp circuit, which is controlled by dual asymmetrical pulsewidth modulation of the primary side, reduces the voltage spikes of main switches and limits the voltage stress of ...

A breakdown voltage doubler for high voltage swing drivers [PDF]
Proceedings of the IEEE 2004 Custom Integrated Circuits Conference (IEEE Cat. No.04CH37571), 2004 A novel breakdown voltage (BV) doubler is introduced that makes it possible to generate high output voltage swings using transistors with low breakdown voltages. The timing analysis of the stage is used to optimize its dynamic response. A 10 Gb/s optical modulator driver with a differential output voltage swing of 8 V on a 50 /spl Omega/ load was ...

A low-voltage voltage doubler without body effect [PDF]
2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008 A voltage doubler, which avoids body effect and then improves rise time and efficiency even with 1 V power supply, is presented. This art is designed for word line boosting, using 0.18 um EEPROM technology. Not only the voltage doubler can work with capacitive load normally, but also it can supply load current and achieve higher efficiency.

Analysis of Voltage Doubler Behavior of 2.45-GHz Voltage Doubler-Type Rectenna
IEEE Transactions on Microwave Theory and Techniques, 2017This paper describes the voltage doubler (VD) behavior of a 2.45-GHz VD-type rectenna. An important feature of the developed VD-type rectenna is the absence of the charge pump capacitor that is present in conventional VDs. Based on the circuit simulation and measurement results, the developed VD-type rectenna shows drastic improvement to the radio ...

Flyback battery equalizer with voltage doubler rectifier [PDF]
8th International Conference on Power Electronics - ECCE Asia, 2011 In this paper, a new flyback battery equalizer employing a voltage doubler rectifier is proposed. The proposed circuit transfers electric charges by utilizing the resonance between the transformer leakage inductor and secondary capacitor. Therefore, the proposed battery equalizer can reduce the switch turn off loss and snubber loss by a sinusoidal ...

A voltage-sensorless PFC voltage doubler
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012This paper proposes a voltage-doubling rectifier, or voltage doubler, with power factor correction (PFC) function and without voltage sensors on the ac and dc sides. The rectifier only uses an ac-side current sensor. The voltage information required for the PFC control is obtained from the ac-side current and its derivative in the on and off durations ...
