This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

The distribution system, a key subset of the overall electric grid, provides power to residential, commercial and industrial customers. Voltage and reactive power management and control have been done ...

The LP2951 voltage regulator is commonly used in applications requiring a preset output voltage, which can easily be configured using two resistors. The device provides low dropout regulation over a ...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

CPF 2.0 was released more than a year and half ago, yet the majority of the designs are still done with CPF 1.1. This is one of those good news/bad news situations. The good news is that CPF 1.1 is ...

The Solution As part of the U.S. Department of Energy and EPRI “Turbine Verification Program,” Enron Wind has developed a closed-loop power plant voltage control called “dynamic VAR (DVAR).” The DVAR ...

In early 2006, KCP&L executives looked for ways to reduce system peak demand. The distribution automation engineering group proposed a voltage reduction option called dynamic voltage control (DVC).

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...
