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 ...

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 ...

Lab-tested solar module performance has improved over the last year, according to data from US-based technical advisory firm Renewable Energy Test Centre (RETC). In its 2025 PV Module Index Report, ...

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 ...

Even though the cables between a source supply and a regulator are basic dc, some basic issues must be addressed to ensure viable results and test integrity. Every engineer knows that a stable, ...

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 ...

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 ...
