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 ...

In the world of power electronics, most instrumentation-grade devices contain a source function and a measurement function. A high-performance power supply is a one-box solution that includes 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 ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...

The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations.

Nuisance shocking — the unpleasant sensation that a person or animal can experience when they inadvertently get between an electrically energized point and ground — can be something of a mystery.
