High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

For the past couple of days 2 of the UPS'es in my house have been clicking like there is a line sag. The UPS'es are on completely different circuits in the house, but both are pretty basic "Connext" ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

In response to the requirements for electric vehicle road testing, Windhill Technology has collaborated with Germany's IPETRONIK to launch an electric vehicle high voltage testing solution.Electric ...

This file type includes high-resolution graphics and schematics when applicable. Bob Zollo, Product Planner, Power and Energy Division, Keysight Technologies Power-supply transient recovery time is ...

One of the most important specifications of an op amp is its input-offset voltage. You can null out this voltage on many op amps, but the problem with determining the input-offset voltage is that the ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.
