Automatic voltage regulator using an AC voltage-voltage converter

IEEE Transactions on Industry Applications, 2000
Voltage sags and extended undervoltages are one of the main concerns of industry today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap-changing transformers used in distribution systems have proven to be inadequate in solving these ...

Low-voltage CMOS voltage squarer

2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009
A 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.

High voltage capacitive voltage conversion

2018 IEEE 30th International Symposium on Power Semiconductor Devices and ICs (ISPSD), 2018
A novel high-voltage, ultra-high efficiency monolithic DC-DC Converter is presented. The disclosed architecture was integrated in the X-Fab XT018 SOI process using lateral Super Junction NMOS devices for up to 400V operation. Buck or boost voltage conversion is realized using high-voltage switched-capacitor and gate-driver techniques enabling ...

CMOS voltage reference based on threshold voltage and thermal voltage

Analog Integrated Circuits and Signal Processing, 2009
A fully CMOS based voltage reference circuit is presented in this paper. The voltage reference circuit uses the difference between gate-to-source voltages of two MOSFETs operating in the weak-inversion region to generate the voltage with positive temperature coefficient. The reference voltage can be obtained by combining this voltage difference and the

High Voltage Versus Low Voltage

Physical Therapy, 1986
To the Editor: The conclusions stated in the article “High Voltage Versus Low Voltage Electrical Stimulation: Force of Induced Muscle Contraction and Perceived Discomfort in Healthy Subjects” (Physical Therapy 66:1209–1214, 1986) contradict an extensive body of literature1–5 that suggests that optimal pulse duration for neuromuscular stimulation in ...

Voltage/Voltage Filters

2018
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!

High voltage insulators

Electrical Engineering, 1934
In this description of the manufacturing processes for suspension insulators, from design and research to finished product, is given a comprehensive list of the laboratory equipment required for adequate testing. Methods of testing for defects and the manner of assembly are sketched, and the need for further standardization is mentioned.

Integrated multivalue voltage-to-voltage converter

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
A 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.

High-Voltage LEDs

2013
In this chapter, the basic mechanisms, opto-electrical characteristics, variety designs, and development process of the high voltage light emitting diode (HVLED) and alternating current light emitting diode (ACLED) were extensively discussed. Some important issues, such as the efficiency drooping, flickering illumination, harmonic distortion limitation,
