Isolated voltage-boosting converter
2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014In this paper, a single switch isolated voltage-boosting converter is presented, which is derived from the traditional flyback converter and charge pump concept. The proposed converter possesses an output inductor, so the output current is non-pulsating.

A Novel voltage-boosting converter with passive voltage clamping
2008 IEEE International Conference on Sustainable Energy Technologies, 2008In this paper, a new voltage-boosting converter, combining the charge pump and the coupling inductor, is presented, together with a passive voltage-clamping circuit which pumps some portion of the snubber energy to the output so as to increase the efficiency at light load.

High Voltage-Boosting Converters Based on Bootstrap Capacitors and Boost Inductors
IEEE Transactions on Industrial Electronics, 2013In this paper, novel high voltage-boosting converters are presented. By changing the connection position of the anode of the diode and by using different pulse-width-modulation control strategies, different voltage conversion ratios can be obtained. These converters are constructed based on bootstrap capacitors and boost inductors. Above all, two boost

A clock boosting scheme for low voltage circuits
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008Limitations in operation of analog switches at very low voltages have caused many problems in design of these types of switched capacitor circuits and data converters. In this paper by modifying a recently proposed clock boosting circuit, we could obtain a new structure with better performance for very low voltage circuits. This method requires simpler

A Boost Converter With Voltage Multiplier Cells
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006This paper introduces the use of the voltage multiplier technique applied to the classical non-isolated DC-DC converters. The major benefits obtained with the integration of voltage multipliers with classical converters are the operation with high static gain, reduction of the maximum switch voltage, zero current switch turn-on and minimization of the ...

Modeling and Voltage Regulation of Boost Inverter
2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018A better performing, non-ideal high single stage inverter for generating a regulated, lower level THD ac output voltage which is greater than the unregulated dc input voltage is suggested in this literature. This work is developed in contrast to the traditional Voltage Source Inverter, which always generates lesser ac instantaneous output voltage with ...

Boosting of the output voltage of a galvanic cell
Electrochimica Acta, 2018Abstract The output voltage of a galvanic cell can be increased by insertion of two pairs of anodes and cathodes into a single volume of an electrolyte. The anode from the first pair and the cathode from the second pair are galvanically connected using external wire conductor. Two cells connected through such short circuit performed as separate units

Direct voltage control for boost converter
(ICEEE). 1st International Conference on Electrical and Electronics Engineering, 2004., 2005Control of DC/DC Converter has been widely discussed in Power Electronics and Control literature. Here, continuation of direct voltage control applied to DC/DC converters via a simple theoretical analysis and practical results are presented, which come into view as a novel way of Boost analysis.
