Voltage Quality Improvement in Low Voltage Distribution Networks Using Reactive Power Capability of Single-Phase PV Inverters

IEEE Transactions on Smart Grid, 2019
The rapid growth of residential rooftop photovoltaic (PV) systems may cause significant power quality problems, such as severe voltage fluctuation and unbalance which can restrict further PV integrations to the network.

A low-power low-voltage MOSFET-only voltage reference

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
A low-power low-voltage MOSFET-only voltage reference featuring very good temperature stability and referred to the positive power supply is proposed. It compensates for the temperature dependence of a gate-to-source voltage of an MOS transistor working in the weak inversion region with a proportional-to-absolute-temperature voltage generated by a pair

Low Power, Low Voltage, Low Drop-Out On-chip Voltage Regulator

2020
Extremely low power, low voltage complete on-chip low drop-out voltage regulator (LDO) is presented. The LDO receives an unregulated supply of 0.5–1 V and regulates it to 0.4 V nominal output utilizing a 0.1 V on-chip reference voltage. A load capacitor of just 1pf is assumed to be present at LDO output. Designed voltage reference and complete LDO were

A low voltage CMOS low drop-out voltage regulator

SPIE Proceedings, 2009
A low voltage implementation of a CMOS Low Drop-Out voltage regulator (LDO) is presented. The requirement of low voltage devices is crucial for portable devices that require extensive computations in a low power environment. The LDO is implemented in 90nm generic CMOS technology. It generates a fixed 0.8V from a 2.5V supply which on discharging goes

A low-voltage low-power voltage reference based on subthreshold MOSFETs

IEEE Journal of Solid-State Circuits, 2003
In this work, a new low-voltage low-power CMOS voltage reference independent of temperature is presented. It is based on subthreshold MOSFETs and on compensating a PTAT-based variable with the gate-source voltage of a subthreshold MOSFET. The circuit, designed with a standard 1.2-/spl mu/m CMOS technology, exhibits an average voltage of about 295 mV ...

Understanding the Low-Voltage Hysteresis of Anionic Redox in Na2Mn3O7

Chemistry of Materials, 2019
The large-voltage hysteresis remains one of the biggest barriers to optimizing Li/Na-ion cathodes using lattice anionic redox reaction, despite their very high energy density and relative low cost....

Identifying Topology of Low Voltage Distribution Networks Based on Smart Meter Data

IEEE Transactions on Smart Grid, 2018
In a power distribution network, the network topology information is essential for an efficient operation. This network connectivity information is often not available at the low voltage (LV) level due to uninformed changes that happen from time to time.

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 ...

Low-Voltage Low-Power Amplifiers

1995
Low-voltage and low-power amplifiers are strongly limited in dynamic range (DR) and bandwidth (B). The maximum dynamic-range/supply-power ratio is restricted to DR/sub max//P/sub sup/ = /spl pi//16 kTBe by thermal noise in resistors. To obtain this maximum value, several rail-to-rail (R-R) input stages and R-R output stages biased in class-AB are ...
