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 ...

Flyback battery equalizer with voltage doubler rectifier

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 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

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.
