March 23, 2014. Keithley Instruments Inc. has introduced two high-voltage power supplies optimized for high-voltage device and materials testing and high-energy physics and materials science research.

When selecting a power supply, one of the most important functional requirements of the product is its EMI performance. AC/DC power supplies are the interface between the end-product electronics and ...

Over the years, the need for increased reliability of electrical systems is no secret to those in the electrical industry. Data centers, hospitals, emergency call centers, government buildings, and ...

Every engineer knows that a stable, well-regulated power supply is needed to perform reliable and consistent circuit and subsystem tests. But what about testing a new power-supply, regulator, or ...

Damage to a relay contact after cyclic current loading. A better understanding of inverter reliability will help boost performance and reduce costs. Image: Fraunhofer IMWS. Inverters are critical to ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

An effective and long-lasting power supply is the backbone of any IoT device. Switch-mode power supplies (SMPSs) are undoubtedly good for powering IoT devices, but most of them are bulky and expensive ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

Decreased system reliability due to overloaded power supplies is a common engineering challenge. In this Q&A-style article submitted by Allied Electronic & Automation, David Norton, technical ...

We recently noticed a very cool-looking series of power supply modules on a few of the Chinese deal web sites. Depending on the model, they provide a digitally-controlled voltage with metering. You ...

A research team at the Fraunhofer Institute for Building Physics IBP, and at the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, is in the process of developing a renewable ...
