According to a Norwegian group of researchers, the reactive power capability of three-phase voltage source inverters can help to reduce problems caused by the intermittent nature of solar power on ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

Today, we share the report: Digital Technology Solutions for New Distribution Networks Based on Low and Medium Voltage Intelligent Devices and Systems in 2025. The report consists of: 25 pages.

James Gibert, associate professor of mechanical engineering, and Hongcheng Tao, postdoctoral researcher, observe their test apparatus as it generates an electric charge by rubbing two surfaces ...

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 ...

Scientists in Belgium have investigated how perovskite absorbers used in solar cell degrade under three different stress test types and have found that the interface between the perovskite layer and ...

The effects of an electric shock vary depending on its source and severity. For example, shocks from light switches may be mild, while contact with industrial power sources can cause severe effects.

Sources with knowledge of U.S. Immigration Enforcement's operation at the Hyundai megasite provide new details.
