Integration, with respect to time, of a varying voltage is accomplished by counting the revolutions of the output shaft of a rate servomechanism. Accuracy of the order of ±0.1 percent over a 100-fold range of input voltage is obtained, with speed of response ample for many purposes.

Low-voltage CMOS voltage squarer
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009A voltage squarer based on bulk-driven PMOS transistors is proposed in this paper. Circuit topology employs a voltage attenuator and the quadratic I D /V G characteristic of a MOS in saturation. The squarer was designed with a 0.8V supply voltage using standard 0.35um CMOS process, which offers large value of threshold voltage.

Integrated multivalue voltage-to-voltage converter
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003A charge pump circuit has been developed. It can give high voltage pulses for on-chip programming EEPROM. The charge pump circuit uses a symmetrical structure and is designed to offer two possible output voltages, power supply or alternatively triple power supply, which is needed for the memory cells we use.

A high voltage split source voltage multiplier with increased output voltage [PDF]
2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015 Building on the Half-Wave Cockcroft-Walton voltage multiplier, a topology is proposed that consists of several voltage multiplying sections fed separately at their inputs and whose output voltages are summated across the load. The proposed topology can attain over m times higher voltage gain (m being the splitting level).

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 ...

Analysis Of Voltage Regulators With Boost Voltage
2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019The article analyzes the approaches to development of AC voltage regulators based on schemes using boost voltages. The influence of the voltage regulation requirements on the topology AC voltage regulators is considered. An assessment of influence of the AC voltage regulator's topology on its operating modes are presented.

Detecting transient voltage stability and voltage sag
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2004This paper presents method to discriminate between transient voltage stability and voltage sag. The discrete wavelet transform (WT) is a powerful tool in the analysis of the transient phenomena in power systems because of its ability to extract information in both the time and frequency domain.

On voltage stability regions and voltage secondary control
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003This paper presents some new results on the geometry of the reactive load-flow problem. These results have implications in order to asses the system margin to the voltage collapse and to design a secondary voltage control aimed to avoid the voltage collapse.

Most of the treatment in the text so far covered the special case of the transfer function which happened to be the impedance one. In that case, input is current and output is voltage. While that is one of the most relevant cases in circuit theory, it by no means is the only one!

The voltage-sensor structure in a voltage-gated channel
Trends in Biochemical Sciences, 2005A recent electron paramagnetic resonance study of KvAP, a prokaryotic voltage-gated channel, in its lipid native environment has revealed the location of the transmembrane segments, the connecting loops and the relative position of the voltage-sensing charges.
