The vulnerability of PERC modules to LID and LeTID is well known and among the reasons the industry is moving towards N-type technology, which tends to be less affected by the two phenomena. TUV Nord ...

No electricity provider in the world can guarantee an electrical supply that is free from voltage and frequency variations. The possibility of faults occurring in user installations or in the public ...

This three-part series describes how to properly test a DC/DC power supply, and ensure that it works reliably over various operating conditions. This series is intended to provide the designer with a ...

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, ...

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, ...

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 ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

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 ...

Power modules might be the semiconductor industry’s answer to some constant problems. With advanced component integration, optimization, and performance, modules deliver a power solution that ...

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 ...
